Ready to upgrade your 2018+ Jeep Wrangler JL/JLU Stereo?

Here at are our shop in Brookfield, CT, we upgrade Jeep Wranglers stereos all the time – older TJ’s, JK’s and even the new JL body style. Jeep Wranglers are a blast to drive in the warmer months – top down, sun shining, doors off and wind blowing between your toes (don’t tell me you haven’t driven your Wrangler barefoot like this). Add a kick ass stereo to the mix and it adds a whole ‘nother layer of enjoyment to the cruising experience.

Whenever possible, I prefer to plan out a Jeep Wrangler JL stereo upgrade BEFORE my client has even purchased the vehicle. Luckily, most of my clients are repeat customers and they do actually reach out to me prior to buying a new car. Once you go aftermarket, you can’t go back. They know they’re going to upgrade the sound so they typically consult with me to know what options they’ll have prior to purchasing and sometimes this changes what package or options they get with their vehicle.

Through my experience I have found most clients have a common misconception. They assume that they should buy the base model since they plan on upgrading the stereo anyways. That used to be the true in our industry, but as technology has progressed, the method of upgrading stereos has changed. A new category has emerged which I refer to as “Pre-Amp Adapters”. For many newer vehicles on the market, there are these really cool pre-amp adapters available that allow us to simply pop out the stock premium amp and drop in an aftermarket amp (and aftermarket speakers) in its place. This enables us to fully upgrade the audio system without losing any functionality or control and while retaining the OEM head unit and user interface.

Jeep Wrangler JL Stereo Upgrade – which model radio is your JL equipped with?

Jeep offers several different radios and packages for the new Jeep Wrangler JL body style including:

  • 5″ touch screen
  • 7″ touch screen
  • 8.4″ touch screen.

All of these models are offered with or without the factory premium sound option. If your model is equipped with the premium sound option, that makes upgrading the sound in your JL Wrangler a lot easier because it means you can use a pre-amp adapter.

Jeep Wrangler JL Stereo Upgrade – Using a pre-amp adapter

There are several pre-amp adapters available on the market at the moment. I’m a big fan of the PAC Audio AMP Pro 4 series which is also available for many GM, Toyota/Lexus and Ford models.

What is a pre-amp adapter exactly? Unlike a base model stereo, the audio signal coming from the back of your stock radio is digital. It’s just one’s and zero’s, data streaming until it reaches the stock amp. Think of that digital signal as a pre-amp audio signal. Once the signal reaches the stock amp it is converted to analog which is then output to your speakers. The stock amp also has built in crossovers and 9 individual channels for each driver unlike a traditional aftermarket amp.

Ideally, to upgrade the speakers and amp in your Jeep Wrangler JL, you want to intercept that audio signal before it hits the stock amp. That is exactly what these pre-amp adapters do. They catch the signal before it has been processed, while it is still clean, unadulterated and digital and then provides you with a way to connect an aftermarket amp and/or DSP processor to your stock stereo. You can either catch it while it is still digital and then keep it digital by utilizing an amp or DSP processor with Toslink connectivity OR you can convert it straight to analog RCA. This photo from PAC Audio illustrates it pretty well. In our Jeep we also used JL Audio’s TWK-88 for a DSP so that we have full equalization control and time alignment.

There are a few different pre-amp adapters on the market compatible with the Wrangler JL:

In our own 2019 Jeep Wrangler JL MOAB edition (Mojito Green), we used the PAC Audio AP4-CH41 and out of the 3 options listed, this is our preferred adapter. It’s a bit more flexible than the other two options. One cool thing about the PAC Audio piece is you don’t have to go the full DSP route. A lot of Jeepsters are do-it-your-selfers and may have skills for a head unit, speakers and amp install, but lack the knowledge and expertise to set up a 31 band EQ or the digital time alignment included with most DSP processors. You can use the AP4-CH41 just to get a nice clean 5 volt pre-amp signal so you can easily install a nice 5 channel amp, upgrade your speakers and add a sub. A DSP is optional with the PAC Audio adapter; it’s not required nor is it included.

Jeep Wrangler JL Stereo Upgrade – Why can’t you just use a basic line output converter?

Is the pre-amp adapter necessary? Can’t I just use a line output converter? For the premium sound models, no, you really need the pre-amp adapter to do it right. You can’t easily slap on a line output converter for a full system upgrade because you’d have to grab your audio signal AFTER the stock amp where it has already been converted and divided up into various frequency ranges for your stock sub, mid ranges and tweeters. This video from iDatalink actually explains really well why you don’t want to do it that way.

 

If you just wanted to add a sub to the stock system and you have the premium stock sound system, you can go the line output converter route and just grab your signal from the stock sub, but for a full system upgrade, you really want to go the pre-amp route.

Jeep Wrangler JL Stereo Upgrade – Speakers, amp, subwoofer and optional DSP processor

If you are familiar with my recommendations on the JK Jeep Wrangler Stereo Upgrade, then you’re already ahead of the game. Really the same rules still apply. In order to upgrade and really be able to enjoy the sound system in your Wrangler – top up or down – you need:

  • Good, clean audio signal (either aftermarket head unit with high voltage RCA pre-amp OR pre-amp adapter with or without DSP processor)
  • Quality speakers that can handle high power for the front and rear
  • Subwoofer – preferably side mounted or down-firing so bass isn’t lost when top down
  • High powered 5 channel amp to power new speakers and subwoofer

Jeep Wrangler JL Speakers – Sizes and location

Speaker placement in the Wrangler JL is the same as the previous JK models. You should have mid ranges against the dash pad, tweeters on the dash and component or coaxial in the sound bar.

However, looks can be deceiving. Although the grille sizes appear pretty similar to the JK body style, the speaker size has changed in the new Jeep Wrangler JL. Oddly enough, they have gone down in size.

Jeep Wrangler JL Stereo Upgrade - sound bar speakers 4 inch component or coax

The Jeep Wrangler JL is equipped with:

  • 4″ components in front with an oversized tweeter (3.5″)
  • 4″ components or coaxial in the rear sound bar (depending on whether yours is equipped with the 9 speaker premium sound system, 8 speaker system or the base 6 speaker)

Oh, and they are mounted in these cute little ported enclosures:

Only trouble with this size is you are kind of limited in options. There are not a lot of high power handling 4″ components on the market. Audison offers the Prima 4 series mid bass speakers and you can pair that with their AP1 tweeters and add a crossover for the fronts. However, for the money, I prefer Morel (I put a set of the BMW Prima speakers in my 2013 1 series and they’re not bad, but I will be swapping them out for Morel in the near future – they’re a little bright/harsh in comparison to Morel).

Morel has a couple options to choose from and they are both pretty freaking awesome. You really can’t go wrong with either model. The Morel Hybrid 402 Components and the Virtus 402 Components fit quite nicely. The first Wrangler JLU we worked on, we did actually install a set of 6.5″ components in the front and modified the housings. We had pulled these speakers out from his last Jeep not knowing what size would be in the JL. It was quite a tedious effort, but if there is a specific set of component speakers you want and they are not available in 4″, you really don’t have any other choice than to modify the housing.

If you have the 9 speaker premium sound set up, you would basically order two sets of these component speakers – one for the fronts and one for the rear sound bar. Now technically you don’t have to go with a matching component set in the rear sound bar, you could get away with installing a coaxial such as the Hybrid Integra 402 point source or even one of Morel’s other 4″ coaxial speakers such as the Tempo Ultra 4″ or even Maximo Ultra 4″. In our own Wrangler we went with the Hybrid series front and rear and they are truly fantastic. Morel specializes in speakers and they really do a phenomenal job. They are made in Israel and they are known for their incredible tweeter. It is silky smooth, detailed, articulate and vibrant, but never harsh. It it impeccable.

Jeep Wrangler JL Stereo Upgrade – Amp placement and recommendation

With your pre-amp adapter, you can technically install whatever amp or combination of amps you desire, but I can tell you what has worked well for our shop in countless Wranglers. This amp is what my husband John and I each have in our own Wranglers – the Alpine PDX-V9. I highly recommend it. I’ve used this amp in many high fidelity system installs. It really is an excellent value. It is a compact, high powered and great sounding 5 channel amp. It pushes out 100 watts RMS per channel to the interior speakers and 500 watts RMS to the subwoofer.

This is plenty of power output if you like it loud and clear cruising with the top down. Even on the highway with the top down, you will still be able to hear and enjoy your sound system with this powerful amp. If you are installing this with only the PAC Audio AP4-CH41, and you are not using any separate DSP processor, we recommend you also include their RUXKNOB2 bass knob so you can adjust the sub bass on the fly from song to song.

In most Jeep Wrangler stereo upgrades, we install the amp under the passenger seat. JL Audio has a couple install accessories that we used in our own Jeep Wrangler JL stereo upgrade that you may want to consider to make your install a little cleaner and easier. The part pictured above is an under seat amplifier mounting bracket for the passenger side and the part pictured below is a nice mounting bracket for your fuse holder.

Jeep Wrangler JL Stereo Upgrade Subwoofer Options

What about the bass? Thankfully, JL Audio is on top of the ball and they have already designed two different stealth box enclosures for the 4 door Wrangler JL. This vehicle specific stealth box is available for either passenger or driver side (or both) and features JL Audio’s 10″ TW1 shallow mount subwoofer.

I know not everyone has the $750 to shell out for a sub like this, but if you can swing it, go for it. This is the best way to add bass that doesn’t take up any room, is clean, tight, punchy and loud enough to hear over wind and road noise. Bonus – if you do buy this subwoofer you are also supporting American jobs. it’s made in America, right in Miramar, Florida (woofer and enclosure).

If you need a more budget friendly option and you’re working with the base 6 speaker system, you could consider using Alpine’s (made in China) PWE-S8 under seat amplified subwoofer. That is a great amplified subwoofer I have used in many Wrangler’s, but keep in mind it’s only 120 watts RMS so it’s pretty similar in output to what the stock premium subwoofer sounds like. It’s not nearly as powerful, deep or punchy as the JL Audio stealthbox, but it still makes for a nice improvement over the base 6 speaker system.

Jeep Wrangler JL Stereo Upgrade – DSP Processor – placement and recommendation

If you want fine tune control such as equalization controls, digital time alignment and easily adjustable crossover points, you’ll want to use a DSP processor with your installation. There are many DSP processors on the market. If you use the iDatalink AR you can use an Audison processor or you can use the DSR1 which has the Rockford processor built in. Our shop has tried many different brand processors on the market – Audison, Alpine, Rockford Fosgate, JBL, Audio Control, Helix, Metra, etc. Out of everything we’ve tried over the past 20 years, our favorite is still the JL Audio Twk-88. It just has the best sound quality and most versatility. Our only complaint is you do need a laptop to set it up. It would be nice if it could be adjusted through an app.

The Twk-88 comes with a DRC-205 which acts not only as your master volume control knob, but also your sub level control (it has an inner and outer ring) and your listening preset control. You can see in the pic above that we have ours mounted where an outlet used to be. When John and I are cruising together, he pushes the knob in and the color on the knob ring changes to indicate we’ve switched from listening preset number one (which he set up for him, the driver) to listening preset number two (which he set up for driver and passenger). I believe with the JL Twk-88 you can have up to 4 listening presets.

Jeep Wrangler JL Stereo Upgrade – Recommendations for non-amplified models

If your Jeep is equipped with the non amplified 5″, 7″ or 8.4″ screen, and you’re happy with the features of your radio and the user interface, you’re still going to want to do some type of DSP processor with your aftermarket amp and speakers. In these models, you can’t really eliminate the stock amp since it’s built into the radio. Anything you attach to your stock radio has to grab its signal after the amp. So you need a fancy line output converter to take that stock stereo analog signal and convert it into a nice clean pre-amp signal.

If you like the idea of the JL Audio Twk-88, that is still an option, but you’ll want to add their Fix-86 to it. The Fix-86 will take speaker level out from your factory radio, analyze it and clean it up so you have a nice clean, pre-amp signal to work with. Technically you could just use the Fix-86 on its own for a high quality, 6 channel line output converter (the fanciest and best on the market IMO). We have done many installs with the Twk-88 and Fix-86 and several installs with the Fix-86 alone. Whether alone or combined, these products always produce an extremely clean sounding solution for tacking an aftermarket amp on after the stock head unit. We never have any kind of background hiss at all which can be a common issue whenever adding an amp to a stock sound system. If you do opt for the Fix-86 on its own, be sure to add the DRC-205 control knob (not included).

Alternatively, another contender would be the more budget friendly Metra AX-DSP which utilizes a T-harness for installation. I have used the Metra AX-DSP in another vehicle and for the money, it’s a great way to tackle a full system upgrade – especially in a vehicle where you can’t or don’t want to change the head unit. One thing I did not like about it is in the previous car we tried this in, we did have a small background hiss which we could not eliminate. It was faint and only noticeable with the volume next to nothing, but still it was there. The install application was slightly different from the Wrangler JL in that it was in a Honda with a premium sound system. I have not tried the Metra AX-DSP in a non amplified vehicle, but I’m hoping it may work better in this type of application.

Jeep Wrangler JL Stereo Upgrade – Aftermarket Head Unit Options

If you have the base model, non amplified 5″ screen, you would probably prefer to replace the radio so that you can get better features like CarPlay and Android Auto. In all likelihood, such a head unit would also have a nice clean pre-amp output. However, as of this writing, Metra has not yet made a stereo installation dash kit for this vehicle, but I am sure they are working on it. Technically some of the wiring parts are available, so if you wanted to make a custom dash kit to install an aftermarket head unit, you could, but there are some limitations to be aware of.

Mounting depth is going to be an issue for any traditional aftermarket double din head unit. It’s probably only about 5″. The stock head unit is extremely shallow and there are vents behind it. I think one of the best options for head units currently on the market would be something like the Pioneer DMH-C2550NEX or DMH-C5500NEX. Both of these models utilize a modular system. The screen is a thin and shallow component and then there is a separate sub brain for the radio guts and pre-amp. Both of these models are also iDatalink Maestro compatible. Using the iDatalink Maestro RR and CH3 harness, you can retain functions like steering wheel controls, access to and ability to modify vehicle settings and on screen vehicle info like tire pressure monitoring, battery voltage and read/reset check engine codes. However, at the moment, it doesn’t look like there are any parts to retain the OEM reverse camera (which is most likely CAN bus activated like most Chrysler/Dodge/Jeep OEM cameras so may not be possible to try and cut and splice and trigger on your own). I’m sure a solution will be available soon for both the dash kit and reverse camera and once it’s available, I will update this post with new details.

Jeep Wrangler JL Stereo Upgrade – Limited options, but only for a limited time

The Jeep Wrangler is one of the most highly accessorized and popular vehicles on the road. It’s only going to be a matter of time until more products hit the market and more options become available. The Jeep Wrangler JL body style is still relatively new, so we are still somewhat limited in accessories and upgrades currently available. However, if you’re looking to upgrade the sound system in your Wrangler JL now, you still have some solid methods and solutions available and I hope you found this blog post helpful in exploring those options. I’m sure there will be many more product solutions in the near future. Until then, I hope this post has been informative to my fellow Wrangler JL owners out there. Please let me know what you think in the comment section below.

    Hi Annie, I just purchased my Rubicon and it has the Alpine premium sound in it. I have the fix86 from my previous car and I was wondering if there is a harness I can plug into the factory amp’s output and input? So with my previous car I had purchased a male and female harness so I can get the speaker level in put from the factory amp’s output and would hook up aftermarket amp’s output to the factory speaker lines. Would you happen to know part number for those harnesses? Made by metra, pac, and etc?

    • June 21, 2019 at 2:52 pm

      Hi Stephen,
      If you have the Alpine premium, the Fix-86 is unnecessary. It’s a good piece of equipment, but not what you want to use in the Alpine premium sound. Would be good for someone with the basic Jeep radio non amplified (in case you want to sell it).

      You can use the Pac Audio AP4-CH41 discussed in the blog post to get your audio signal BEFORE it reaches your stock amp and is processed. The Fix-86 is designed for vehicles where you can’t do that and have to catch your signal AFTER the factory amp. The Fix-86 does a very good job summing signals and cleaning up sound, but in JL Wrangler’s with the Alpine premium sound you can use the AP4-CH41 to catch the audio signal while it’s still clean and digital. It retains warning chimes, Bluetooth, etc. The AP4-CH41 gives you a dedicated 5 volt front, rear and subwoofer pre-amp output. Also with an optional toslink adapter, you can keep signal digital if you’d like and then go into a JL Audio Twk-88 or other processor or amp with optical in and DSP such as JL Audio’s line of VXi amps.

    I just bought a 2019 JL 4 door with the 7 inch screen with the base speakers. I’m looking to upgrade and found this system from Alpine. https://www.quadratec.com/p/alpine/full-sound-system-upgrade-jeep-wrangler-unlimited-jl

    I love the plug and play install concept, sounds easy enough for me to do without any experience upgrading car stereo systems. I figure, I can watch a youtube install videos and get it done.

    I don’t want to over pay but since I’m considering making the sound system upgrade I want to get quality sound.

    I don’t see any other full system upgrade kits like this Alpine that seem easy enough for a novice.

    I did read that Alpine decided not to upgrade the base main speakers stating that they are pretty good just not in the highs and lows hence why their upgrade focuses on the tweeters and subwoofer only. I have no idea if it is better to upgrade the main speakers too or not.

    Any suggestions on what I should look at for complete systems or combination of products to do an upgrade?

    Much appreciate your advice!

      Hi Scott, have you been on the JL forums? There is a speaker upgrade thread on there I’ve commented a lot on there along with a lot of other folks and the consensus seems to be pretty much what I’ve stated in the article. You may find it helpful.

      Ideally you’d want to do something like the Fix-86 from JL Audio along with a quality aftermarket 5 channel amp with or without DSP control (ideally with a DSP such as JL Audio’s VXI amps with built in DSP Tun software or another high powered amp like the Alpine PDXV9 and separate DSP like the JL Audio Twk-88) and some type of subwoofer. Here’s the deal with that Alpine package. You’re spending a lot of money for easy plug and play t harnesses. Those speakers, the amp and the sub retail combined just under $600. So you’re paying $700 for easy install. IMO, you are much better taking that money and buying better quality components and going to a true professional installer familiar with the vehicle and equipment.

      For reference, there was someone on the forum who had done this upgrade and was not happy with it, he complained of speakers popping at higher volumes which is exactly what I would expect to happen if I put more power to a very basic stock 4″ driver. There are very few vehicles I would do this in, the only cars I’ve really had success in amping stock speakers are BMW’s – putting cleaner power to the stock under seat subs while upgrading the main 4″ component works. But I can’t see that package sounding like a $1300 upgrade. I just think Alpine has it priced way too high for what it is. I’m an Alpine dealer and don’t sell it, but I love selling other Alpine products where they’ve done well like the PDXV9, Type X speakers and iLX-W650.

      If you have a JL Audio dealer in your area, you may want to consider a VXI 4 channel amp, better quality speakers and the PWE-S8 subwoofer (which can be routed and audio tuned through the VXI amp). Price wise, depending on what speakers you go with and going labor rate in your area, that’s probably going to be more like a $3200 – up sound system. However, in terms of sound quality and bang for your buck, that is going to be leaps and bounds higher quality upgrade. I just have a hard time justifying paying that kind of money for the Alpine set up, I think it would make more sense if it was priced around $800-$900. That’s just a lot of money on nice connectors and brackets for $600 worth of equipment (consists of PWE-S8 – $299, KTP-445U – $169 and SPR-T10W tweeters – $119). There really are no other novice easy install systems on the market which I am sure that’s why they feel comfortable with the price, but knowing what the hard cost of each component is in that package makes it a lot harder for me to justify it.

    2019 4 door Wrangler Rubicon with 8.4” Premium System. Is the 12 channel amp that comes in this system a high quality amp that needs a dsp, or should the amp be replaced. Looking to use Morel 4” Hybrids front and rear. Also, what about the quality of the 10” sub that comes in the Premium System, does it need to be replaced?

    • June 12, 2019 at 10:54 am

      Hi John, we do this every day so I doubt we could ever live with a stock premium sound system and ever be happy with it. It’s probably better than the previous Jeep premium sound system, but it’s still just a stock premium sound system, it’s nothing special or fancy in terms of quality of the amp or speakers.

      We replace the stock amp in the premium models using the Pac Audio pre-amp adapter described in the article. The JL Audio VXI amps with built in DSP are popular, but not quite as much power output as something like the Alpine PDXV9 which we had in our last Jeep and what I have in my 2-door 2014 Wrangler and am totally happy with in terms of quality and output. The PDXV9 could then be combined with a separate processor like the Twk-88. It depends on how loud and clear you like it and how much control you want over the sound. We like it loud with the top down and we like having different EQ presets such as one for driver only, driver and passenger and then same thing for top up vs top down. So we currently have in our own 2019 Wrangler 4 door MOAB:

      -Pac Audio AP4-CH41 pre-amp adapter
      -Pac Audio toslink adapter APA-TOS1 (keep signal digital to aftermarket amp/processor)
      -JL Audio VX 1000/5i (75 watts x 4 plus 600 x 1) running front speakers and subs with DRC-205 control knob (to change presets and sub level control)
      -JL AUdio XD 200/2 (75 watts x 2 (running rear speakers)
      -JL Audio Stealth boxes (driver and passenger side)

      If you are looking to do your upgrade in phases you could potentially replace the speakers first, but you’ll never get the full potential of those Morel speakers until you replace the amp. You may be able to get away with re-using the stock sub and just putting cleaner power to it with an aftermarket amp, we have done that too, but it’s just a very boomy enclosure, not very tight or punchy so that would not be my first choice.

      Hi Alan, we haven’t had a 2-door come through the shop yet, but as soon as we do I will be sure to update the post ;)

    Thank you for such a comprehensive write-up! I have the 12ch Alpine system, and I’m looking for a speaker wire harness that will allow me to unplug the speaker wire plug from the factory amp, and connect a harness to that bundle run from my amp under the seat. I’m looking to keep the little factory amps in place so I can more easily revert to stock if needed. Is there such an amp bypass adapter that you know of? I actually got the PAC APH-CH01 AmpPro Harness, but it’s not looking like it’s the right one.

    Basically looking to do this>
    Headunit>AMP Pro 4>TOSLINK>VX800/8i>speakerwire to harness>to unplugged factry amp speaker output wiring.

    -Thank you

    • June 6, 2019 at 3:55 pm

      Hi John-Patrick,
      I know what you’re looking for, but I am not aware of anything on the market just yet. And you’re correct, that APH-CH01 is only compatible with the previous JK body style and it looks like the 2018 2-door JL, but not the 4 door (I’m assuming yours is the 4-door, I had made the same error when ordering parts for our car and when I drilled down saw it wasn’t listed for the JLU). To keep it clean you may want to consider using bullet style crimp connectors where you break the connection so you can easily reconnect everything if you sell the car and need to go back to stock.

    Will utilizing the Pac Audio AP4-CH41 Pre-Amp adapter still allow full functionality of the 8.4 Uconnect headunit? Wondering if the phone connections and mic will still be routed to the correct location.

    • May 30, 2019 at 8:35 pm

      Absolutely, retains full functionality, no issues. I annoy my husband all the time when I call him when he’s listening to his stereo, but he can hear me and I can hear him loud and clear just like factory. Phone calls, warning chimes, reverse sensors, etc. all work exactly as they did before. The only thing I think you might lose (and I haven’t even checked because we’re doing everything through the JL Audio Twk software) is you might not have fader control. I will double check.

    • May 30, 2019 at 8:54 pm

      Okay, talked with hubby John, fader control depends on how you use the AP4-CH41. If you use it as it and keep it analog and use the front, rear and subwoofer 5 volt pre-amp, you will still have fader control. But if you keep it digital (cleaner sound) with the toslink adapter then you lose fader control, but still have balance. That’s really the only difference.

    I had a few questions about using the Morel Hybrid speakers. I have a 2018 JLU Wrangler Sport with the base audio system and 5″ Uconnect3 head unit.

    1) Hybrid 402 vs. 502/602:
    You mentioned that you did one install with 6.5″ components, but that it was a lot of work to make the necessary modifications. Would the 5.25″ components be significantly easier, or would it really be almost as much work? The larger Morel Hybrid drivers would increase power handling and frequency response over the 402s, but would it be worth it? There’s not a huge difference in speaker price going up to the larger drivers.

    2) Active vs passive crossovers:
    I’m seriously considering just disconnecting the rear sound bar rather than upgrading the back speakers. This gives me a couple options for the front. One option would be to stick with the Morel passive crossovers and bridge the amp to provide more power to the speakers — especially if I ended up going with the larger drivers. The other option would be to use the TWK-88 (which I plan on using in any case) as a crossover and power the front components with four channels. That would give the DSP some more flexibility in terms of time alignment for the tweeters vs. the mid range. Would I be able to save some money by buying the individual Morel Hybrid woofer and tweeters over the component set, or would it really cost about the same, since sometimes the sets provide a discount over full price for individual drivers? Is there a good reason to favor one choice over another here?

    3) Hybrid vs. Elate Titanium:
    Compared to the Hybrid 502, the Elate 502 is a huge jump in price (close to double), but it wouldn’t cost any more than two sets of Hybrid 402 components for front and rear. I probably wouldn’t want to spend the extra money, but do you have any experience with the Elate series? If I’m not buying the crossovers, that might also reduce the price for getting a set of Elates.

      Hi Scott,
      That’s a lot of questions, all very good ones.

      1) Hybrid 402 vs 502/602. I kind of want to answer this one after we RTA our JLU. We have the Hybrid 402’s, passive crossovers, 5 channel amp (100 x 4 and 500 x 1) and JL Audio 12W6 in a custom downfiring enclosure with a passive radiator. It sounds great, but maybe I am biased so I am curious to see how it compares to the RTA of a similar set up with the 6.5″ drivers. On paper – when properly installed and set up you should not be missing anything especially considering you would be using the TWK-88 to set time correction and possibly crossover points. Either way to go up to a 5.25″ or 6.5″ you’re essentially shaving off the top of the speaker enclosure and fabricating a new top to house the larger speaker. Depending on magnet size, maybe with a different series speakers it might be easier with a 5.25″, maybe you could just dremmel it out rather than do this. From a power handling perspective – 402’s rated at 100 RMS, 502’s rated at 120 and 602’s rated at 140. So if you have an amp that can put out 150 per channel, yeah better off doing the extra work so you can utilize full power potential.

      2) Active vs passive: always nicer to have control over individual drivers. In all my previous vehicles (2003 & 2006 Jetta GLI, 2008 & 2011 BMW 3 series) I never included rear fill, I preferred to run active and with time alignment I never missed the rears. In my 2014 Wrangler, I actually really like the rear fill, I think because it’s not really from behind me but above me, I feel like it does add to the listening experience especially when the top is down or sun rider open. Personal preference there. With the Twk-88 you could always add a 2-channel amp and some rear fill later on, you’ve got 8 channels so you could run active tweeter and mid in front, a coaxial in sound bar (or passive crossover with component) and sub and still have full control of every channel. I don’t think it would be cheaper to buy the mid’s and tweeters separately unless you go with Elate’s. Hybrid 402 woofer pair retails for $409, MT-230 tweeters pair retail for $349, but in the Elate line they specifically offer minus crossover for $200 less.

      3) Hybrid vs Elate – I agree it’s a huge price jump. I explained it to another client this way. It’s like double the price, but not necessarily double the performance. Definitely more refined, clearer and warmer. If you can swing it, it is nice, but not exactly twice as nice. I’ve had a few customers go for Elate and not one of them ever said to me gee I wished I saved the extra money and went with the Hybrid’s. They were happy.

    Would love to know if there are any updates yet on aftermarket decks and mounts for the JL’s?

      Hi Derrick – nothing yet from Metra, BUT, I’m pretty sure something could be fabricated using the stock 7″ trim ring and an aftermarket radio mounting sleeve like the Pioneer ADTVA-133 and possibly some thin ABS plastic. Also – I just learned this today and super excited about it. I mentioned Pioneer’s new hideaway style units would be compatible, but Kenwood’s new DMX7706s and DMX706s are going to feature a super shallow chassis like the Alpine iLX-W650 AND they are iDatalink Maestro compatible so that is probably going to be my go to choice for a radio replacement in these vehicles. Those models are shipping end of this month. Only thing we’ll be waiting on at that point is iDatalink to retain the reverse camera. They are currently working on it, but no ETA at the moment. I’m sure it’s a priority because these vehicles are so popular.
