JL Audio Built In USA 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

Two Stealthbox enclosures are available for your Wrangler — one installs over the driver's side wheel well, one over the passenger side wheel well — and each enclosure is available in black or gray. Most people will be happy with one enclosure, or you can use two if you're looking for high-performance bass.

Each Stealthbox contains one 10TW1-4 4-ohm 10" sub in a sealed enclosure, handling up to 300 watts RMS. A steel mesh grille protects the subwoofer. Installation does not affect hardtop installation.

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

Sound is great! The way it is mounted makes it a bit more difficult to take off the hardtop as the brackets use the same bolt holes. 4 stars instead of 5.

Pros:

Cons:

Its JL no need to say anymore.

Perfect fit. No loss of cargo room. Its JL no need to say anymore.

Pros: no loss in cargo space.

Cons: none

Great sound, but a few design flaws

Robert from St Augustine, FL on 11/21/2017

Crutchfield Customer Review (What's this?)

From a sound perspective, you really can't ask for anything more in a Jeep Wrangler. As long as you adequately power it with a decent amp, you will get some solid bass. That being said, there are a few drawbacks. First, it is designed to be connected via banana plugs. However, on the 2017 Wrangler it is so tight against the rear seat that it will bend and break the mounting posts if you do that. I had to remove those binding posts and replace them in order to make it work. Second, what they don't tell you is that in order to mount this you are making it very difficult to remove your hard top. You essentially replace 2 of the bolts and put a nut on them. So, what used to take 5-10 minutes will now take 4-5X as long. I like to remove my hard top on occasion, and this has made it all but impossible to do so. For some that won't be a deal breaker, but it is definitely worth noting before you buy it. For this much money, I would have like a better mounting mechanism that allowed free removal of the top. After all, that is why we buy these cars.

Won't fit

Crutchfield Customer Review (What's this?)

The mounting hardware that comes with the sub does not work in the 2017 jeep. You can hook up one in the rear of the sub but the seat belt and the front brackets won't work. The front top bracket won't even go onto the recommended bolt in the front.

Cons:

Definite space saver

Dante from Chicago,Il on 7/9/2017

2016 Jeep Wrangler Unlimited

The stealthbox definitely doesn't invade cargo space, but I was slightly disappointed by the sound. I'm hoping it's just the 300 watt amp I'm pushing it with. I'm going to buy the passengerside in the next few days with a more powerful amp. I will re-review once I get the 2nd box and the amp.

Pros: Great on saving space. Delivers very clear music

Cons: One box is not delivering the punch I thought it would

Space Saving Slammer

Crutchfield Customer Review (What's this?)

Can't beat this deal. The box saves so much space and the sun sounds great. This thing slams pretty hard. I could be looking into snagging another one soon

Pros: Great sound Space saving

Cons: Has a rough time with Kevin gates for some reason.. no other artists of any genre I've found... just gates.. I don't get it

Great sound

Pretty good sounding amp for the price. Tucks away for saving cargo space.

Pros: Fits 2017 Jeep Wrangler Unlimited Sport.

Cons: None so far.

Great for saving space, not the best sub for the money though.

Crutchfield Customer Review (What's this?)

I had a JL Audio CS110G-TW3 in the back of my Wrangler, and really wanted more space on the floor, so I bought one 10" stealthbox. Without increasing the gain (that I should have in going from 2 ohms to 4 ohms), I immediately noticed that this 10" is stronger higher in the frequency band, but weaker down low. I ordered another for the passenger side to see if this gets me close enough. 11.03.16 - Update from my first review. I didn't increase the gain when I went from one 2 ohm to a single 4 ohm stealthbox because I was not sure I wanted to keep the single Stealthbox (my amp is tough to adjust). Well, I added the second stealthbox and wired in parallel to produce a 2 ohm load, and it's incredible! I think my OEM radio reduces the low end gain near max volume, that's why I was unhappy with only one. So two stealth boxes sound awesome, and freed up my cargo area. They are still very expensive and make removing my hard top difficult, but overall it's not enough to ding it a star. I love the design and placement of the box, but I am having the same problem as the other guy with the box pushing into the seat. I loosened all the bolts and tightened them with the seat locked, and it's better, but not great. Locking the seat into place is fine now, but to unlock it, you have to throw some weight into it. Overall, I think JL Audio designed a great product, but they could have made the box at least 3 inches deeper to provide more volume for a better driver. And for this price, it should perform better and not interfere with the seat.

Pros: Saves cargo space, firmly mounted and secure.

Cons: Interferes with rear seat, performance is just OK.

Perfect Sub

This little sub blew my mind as well as the installers. It fills my wrangler up with a nice thump with the top on or off.

Installed on 2013 Jeep JK rubicon

KB from Oklahoma on 1/17/2016

2013 Jeep Wrangler Unlimited

I don't usually do reviews but their is so little out there on these Jeep JK speakers. These install on the back wheel well and come with 3 braces for secure mounting. When all 3 mounts are used their is no movement and they are rock solid. I have taken the speakers out and they are heavy and solid. I have my system tuned really for Rock and Roll and Country and only on rare occasions I will put on some Rap. For my preference they are really punchy like sitting in front of a live band so they sound crisp and sharp. Keep in mind I have both Driver and Passenger sides and they are powered by a JL Audio 900/5 amp. It is hard to rate sound on a sub but on Rap songs it will really shake the Jeep, not like 2- 15inch subs but when they hit you have people turing around to see what the hell is back there. These are not stealth in any way but they are clean and stay out of the cargo area. So I would highly recommend these Subs- my biggest fear was that they were loaded with cheap subs but these subs seem really solid. The reason for the reduction of the one star, the speakers can interfere with the seat release. We spent hours installing the whole system and as we get in the back seat to listen the seat clicked locked it was almost impossible to get the seats to release to lay back down. The 2nd issue was that the box had one small strip of Polyfill inside which was not enough- hope this helps get some info out on these.

Pros: Clean, Compact and out of the way. Hard to see how these would get in your way for cargo.

Cons: Rattled ever so slight until more polypill was added. Putting the seat down was a lot harder after install but you can get it down.

Fantastic design

Crutchfield Customer Review (What's this?)

The build quality from JLAudio is fantastic. The enclosure carpeting is a great match for my rubicon. Once installed there is no cargo space lost. The sound quality is fantastic, I considered ordering 2 but right now with the hardtop this is perfect. I'll need to revisit the idea come springtime.

Pros: Great fit no cargo space lost. build quality sound quailty / loudness

Cons: no amp mounting price

Great product

Yes. Works great [ BARRY  Jun 11, 2018 ]
I recommend for you to ask JL audio. I do not think so. All I know is that I believe that if you install this you may not able to recline your back seat if its a JLU. Cause sub wont let you. I bought the passenger side. [ Rafael  Jun 11, 2018 ]

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.

The JL Audio Stealthboxes are all custom made and shipped directly from JL's warehouses upon purchase, so we don't have enough hands-on access with them to determine detailed specifications, including the net airspace. Your best bet to find that information would be to contact JL Audio's support directly at 954-443-1100. I hope that helps.

Each system contains one 10TW1-4 in a sealed enclosure with 300 watt power handling. Each enclosure is wired for 4 ohms (using two achieves a 2 ohm load in parallel). A steel mesh grille is included with each to protect the subwoofer driver. Each enclosure installs above one rear wheel well, with specific models for passenger and driver side. Does not affect hard top installation. [ Brandon  Feb 17, 2016 ]

No the stealthbox Will not limit the seats recline ability. [ HERBERT  Nov 11, 2016 ]
Yes. The speaker is mounted over the rear wheel well behind the back seat. The front seats will not be obstructed. [ CHRISTOPHER  Nov 11, 2016 ]
No drilling is required at all Allen/hex key combination wrench & tourque bit supplied with the jeep is all needed. Great strong sturdy fit. Great build and design [ jamaal  Mar 27, 2016 ]
We mounted ours in a 2014 Jeep Wrangler Unlimited. It came with all the mounting hardware, so no need to drill any holes. [ RICHARD  Mar 26, 2016 ]
No drilling. The same holes for attaching hard top, which are pre-existing even if you do not have a hardtop [ MICHAEL  Mar 26, 2016 ]
No drilling required. It attached to the seat belt bolt and replaces a hard top bolt. [ CHRISTOPHER  Mar 26, 2016 ]
No drilling required at least for the hard top wrangler. The bolts that hold the hard top on are replaced with bolts that are provided with the speaker. Easy install. [ BRANDON  Mar 26, 2016 ]
