Big bass for your Wrangler

The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.

Perfect sound to go with the perfect fit

JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.

The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.

Enjoy enhanced, custom-fit sound

This Stealthbox® enclosure fits in your 2007-up Jeep Wrangler. It installs on the cargo-area floor, raising the floor about five inches. Installed correctly, the enclosure can be easily removed from your Jeep if you need the space or anticipate some serious dirt and mud.

Please check with us before purchasing by using the vehicle selector, or calling an Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as moderate. You should be able to install this enclosure if you have experience with car audio but some vehicles may require modifications.

Perfect Fit and Sound

John J from NY on 9/14/2017

2017 Jeep Wrangler
Crutchfield Customer Review (What's this?)

Fantastic addition to a Jeep Wrangler to get the much needed bass in the vehicle unobtrusively. Dirt Simple install and great sound when coupled with a good amp

Pros: Takes up very little space and has great sound

Cons: Loosing the back storage well, but can be swapped out (tool free) in under a minute if need be.

Sweet Bass

Joseph from Estell Manor, NJ on 7/6/2017

Crutchfield Customer Review (What's this?)

The difference between stock and JL audio is vast. After installing the piece my sound has been the talk of the town... I highly recommend this product if you are looking for the BEST!



Great for a single, low profile, sub

David from Chatsworth, CA on 5/29/2017

2016 Jeep Wrangler
Crutchfield Customer Review (What's this?)

Perfect fit. Paired it with a 5 channel amp running 500 watts to the sub. Mounted the sub control knob near the shifter for easy access. Sonically, the JL performs wonderfully but loses some steam with the sub 30 Hz frequencies and some of the frequencies at the crossover point of 80 Hz. Make sure you've got some solid performing component speakers in the soundbar and fronts to keep up and handle those 80 Hz - 100 Hz frequencies to even out your listening experience. Great sub so far with the hard top on. Taking the hard top off for the summer and hoping the open air sound remains at least partially enjoyable.

Pros: Perfect fit for my Jeep Wrangler Sport. Impressive sound. Easy install.

Cons: Performance below 30 Hz is lacking. Frequencies around 80 Hz are a little sloppy.

Not as good as I thought it would have been from all the other reviews

Kyle from Tampa, FL on 7/12/2016

2012 Jeep Wrangler
Crutchfield Customer Review (What's this?)

I used an amp recommended for this box but, it doesn't sound very tight. A little disappointed after reading the other reviews on this box I thought it would sound much better..

Pros: uses the space in the back, leaving more cargo room

Cons: over priced for the sound quality.

JL Audio Stealthbox®

Scott from Lincoln, RI on 4/26/2016

2012 Jeep Wrangler
Crutchfield Customer Review (What's this?)

I have to admit I had my reservations about dropping this much money on a box and subwoofer but I got everything I paid for, This thing knocks hard even with the Top off and worth the extra money.

Pros: Doesn't take up that much room in the trunk and if you don't know what you're looking for you would never know there's a system in the trunk

Cons: None just buy it you won't regret it

Great Product!!!

Jim C from Cumming, GA on 4/22/2016

2015 Jeep Wrangler

The stealthbox has been an excellent addition to my audio system. The subwoofer provides a clean, great sounding low end in a compact box that allows for maximization of the small amount of cargo space in my JK. The black color matches up to my interior very closely. I paired with the Alpine PDR V75, which fits perfectly in the amplifier cut out on the stealthbox and pushes the sub to the perfect levels. The install was a breeze, fits solid when the rear door is shut with no rattling issues whatsoever. The steathbox really fits its name as potential thieves have no idea that the unit is in the back of my Jeep. Overall, very satisfied and a definite recommendation for anyone considering purchase.

Pros: Great sound, compact, and fits perfectly in the back of my jeep.

Cons: A little on the pricey side, on average $100-$150 above local stereo shop's quote for a comparable build (however no where near the compactness).

JL Audio Stealthbox®

Jenna from Missouri on 1/17/2016

2010 Jeep Wrangler
Crutchfield Customer Review (What's this?)

I bought the Stealthbox after researching several options for my husband's Jeep; no other subwoofers seemed to work well. The Stealthbox fits in the limited area available, blends in with the interior, and leaves plenty of room for the back seat and some storage. A big selling point was the space available in the box for an amp. After getting everything installed, it sounds GREAT. I can't review the sub without an amp, but I can say that even with the stock speakers and head unit, the sound in the Jeep is vastly improved, and you can't see the sub and amp at all. Delivery was quick, the packaging was very sturdy, and the sub sounds awesome; all in all, I'm very pleased with both the product and Crutchfield's service. We'll be back.

Pros: Fits well in the small amount of space available in a Jeep; great sound; additional space for separate amp.

Cons: None so far.

"Basketball punch sound"

unknownguitarist from Largo, Florida on 11/12/2013

Crutchfield Customer Review (What's this?)

I do not listen much to hip hop, or music that shakes your surroundings outside the vehicle. It takes 15' of physical airspace to reproduce bass waves under certain frequencies anyway. What I do like is tight solid punch of the kick drum, of which is referred to as "basketball sound or punch" on high end audio sites like gearslutz. This delivers that. It is hooked up to a JL HD900/5. The amp has a separate volume knob for just the sub, nice touch and I use it a lot.

Pros: Solid punch. Has an area to mount the amp. Ported towards the front, so the sound "crawls" thru under the back seat. Allows the area above it to still be used for placing groceries or suitcases on top. Easy to install. Blends right in with the rest of the interior. Unless you know what you are looking at, it does have the stealth / undetectable going on. I also used a JL clean sweep, cause I wanted to use the stock radio, and leave the Jeep with the top off and not attract curious thieves

Cons: Price was no object for me given the above pros, , but many can get results without the attributes mentioned for less money.

2door Wrangler Stealthbox

Dan from Ottawa on 7/5/2013

Box had a nice fit in vehicle but raddled allot had to screw it down to eliminate vibrations. I found that the bass was not as I expected from a JL product I was hoping for more bass. I powered it with the JL 700/5. I got better bass from a Kenwood sub in a custom wood box from my old system witch cost me a couple of hundred bucks!

Pros: Great fit, clean look

Cons: Box rattles and lack of bass for a JL product.

JL Audio Stealthbox for Jeep Wrangler

Jeff M from Westminster, MD on 4/18/2013

Stealthbox is sleek - only takes up about 4-5" of height in rear cargo area. Allows for maximum storage while achieving great sound. Comes with 10" JL Audio Sub.

Pros: small foot print - allows for maximum storage.



Hands-on research

Product Research


Overview: JL Audio's Stealthbox subwoofer systems are designed to hide away in a specific vehicle. Please enter your vehicle information to confirm fit.

Construction: Stealthboxes are hand-crafted from fiberglass and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of enclosure rigidity and dimensional stability not possible with other enclosure materials, allowing wall thickness to be reduced compared to a typical wood enclosure. This gives you more interior box volume for a given external volume. Fiberglass and AMC materials are very strong and can be molded into very complex shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly into tight spots and minimize intrusion into your vehicle's useful space. Each Stealthbox is laminated, ground, joined, and finished by hand in the USA. Proprietary techniques and materials developed by JL Audio through years of fiberglass manufacturing experience ensure consistent quality and performance.

Woofer: One 10" JL Audio 10W1v3-2, 2-ohm subwoofer is loaded in this enclosure.

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the W1v3-2 motor remains linear over a long excursion range, and also maintains a stable, fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
  • Vented Reinforcement Collar: The Vented Reinforcement Collar (VRC) is a composite structure that addresses two issues related to reliability:
    • Stress Relief: By reinforcing the critical junction between the cone, voice coil and spider, the VRC reduces failures due to glue breakdown or material weakness. It does this by increasing adhesive contact area and providing stress relief to the spider material at excursion extremes.
    • Air Flow: The VRC also features slots that facilitate air flow directly onto the voice coil windings, thus reducing thermal compression effects and enhancing reliability.
  • Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v3-2 features a unique spider, coil and terminal subassembly, assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. This type of assembly ensures precise lead wire length, lead wire entry and exit angles, and coil/spider alignment.
  • Elevated Frame Cooling System: The elevated frame design of the W1v3-2 delivers cool air through slots directly above the top-plate to the voice coil. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

You can also contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Kenny  Sep 01, 2017 ]  Staff
I don't believe the factory head units have the recommended power output for the subwoofer. I still have my factory unit in the dash (with CD player, XM / Sirus Radio and Bluetooth connectivity for my iPhone), but ran a 5 channel amp that I purchased here on Crutchfield to power the sub and add some punch to my entire system. The 4 channels run 100 watts to the front and rear, left and right speakers each; and the 5th channel is a dedicated subwoofer channel with 600 watts of power going to the JL audio box. I wouldn't recommend just running the sub from the head unit. The amp, speaker wires and power kit, together, cost me around $350 during one of the sales and it was definitely a great investment for a solid sound upgrade. [ David  Sep 01, 2017 ]
This stealthbox is not rated to work in your Jeep. However, we have some that can work. You can see one of them here: Feel free to contact an advisor on 1-800-324-9695 for a personal recommendation on one. My Bio: [ Paul  Aug 07, 2017 ]  Staff
Just the shallow 10s [ MICHAEL J  Dec 27, 2016 ]
Even if you found a 15" sub that worked in the volume of that box, I don't see anyway you would be able to just open up the hole more. Espically since the box has all sorts of curves and contours, I don't know how well any other sub would even drop in without banging into various edges. [ STEVE  Dec 26, 2016 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Kenny  Sep 16, 2016 ]  Staff
Thanks for the heads up, Steve! JL Audio makes and ships the Stealthbox enclosures directly from their warehouses so our product researchers aren't able to measure the amp tray dimensions on their own and JL Audio doesn't include that information in the specs or owner's manual. That said, we verified that Steve purchased this same model from us and thus would have hands-on access to the amp tray; so the dimensions he listed in his response (8.25" x 12.25") should be accurate. You can also try contacting JL Audio's Support at 954-624-0113 for more information. I hope that helps. My Bio: [ Larry  Feb 21, 2016 ]  Staff
8.25" x 12.25" perfect fit for my alpine pdx-v9. [ STEVE  Feb 20, 2016 ]
