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 2002-up Dodge Ram Quad Cab trucks. It fits under the rear-bench seat on the passenger side. This Stealthbox® includes one 10" 2-ohm W3v3 subwoofer from JL Audio. Please check with us before purchasing by using the vehicle selector on our site, or calling a Sales Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as low. You should be able to install this enclosure if you have any experience with car audio.

Note: You may need to cut into or remove part of the underseat carpet and/or carpet padding in some models. This Stealthbox® enclosure will not fit Mega Cab models.

Product Highlights:

  • Stealthbox® custom-fit subwoofer
  • sealed fiberglass enclosure
  • 10" 2-ohm W3v3 subwoofer
  • fits under rear-bench seat on passenger side
  • power handling: 100-300 watts RMS (1,000 watts peak power)

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Boom in the truck

Written By Gary, Texas on Saturday, October 10, 2015

Crutchfield Customer Review (What's this?)

Bought this for my 2015 Ram 1500 CC and it is very nice. Can't go wrong with JL audio. Paired with JL 250 watt amp and it will definitely put out some bass. I barely have it turned up and the sound out of it is second to none.

Pros: Its JL Audio, does what its supposed to do, Ease of installation.

Cons: Price

Crutchfield Customer Review (What's this?)

Amazing bass from a 10" sub. Combined with my JL Audio XD700/5v2, I now have the system I've wanted for years. My 2013 Ram 1500 kicks it out! Any type of music sounds great but I'm biased to Satriani, Bonamassa, and Chili Peppers. This is the cleanest bass I've ever heard

Pros: Amazing bass! Strong and clean!

Cons: None but you might want a remote volume control for the amp sub output. Some songs don't call for as much bass as this puts out

Mighty bass in a small package!

Written By Andrew H, Bellevue, NE on Saturday, June 27, 2015

Crutchfield Customer Review (What's this?)

A lot of driving bass from such a small package. Steep price but you are def paying for quality! The reputable W3 is great from my 2500 quadcab and has plenty of power to blast over the sound of my straight piped diesel. Pairs well with the JL XD700/5v2 if you're looking to power door speakers as well. Rock on!

Pros: Amazing power and performance in such a small/clean/and factory looking package!

Cons: PRICE!!!

Crutchfield Customer Review (What's this?)

Fits perfectly in my 2012 ram 1500. Sounds fantastic with plenty of thumping bass. Just make sure your sub amp is 2 ohm

Pros: ease of installation, quality construction, Killer bass

Cons: A little on the high side for price, Has to be 2 ohm amp or it will fry your amp if it is not!!! I discovered this the hard way and it turned a 4 ohm amp inside out!

Written By Matt P, Colorado on Thursday, April 16, 2015

Crutchfield Customer Review (What's this?)

Great speaker. Shipping was a bit of a hassle though. It seems as if there was some disconnect between Crutchfield and JL Audio as my apartment number was not passed along so I ended up having to go out of my way to pick it up, other than that there were zero issues.

I put this in a 2009 Ram 1500 Quad Cab and installation was a breeze. The speaker itself is fantastic, I hooked it up to an Apline PDR-V75 and was not disappointed. I am blown away by the performance, it's amazing that this is all coming from a 10" speaker. I have had plenty of subs from different companies (Kicker, Alpine, Rockford) and none of them hold a candle to JL. Though the bass isn't as "loud" as the others, you can actually hear and distinguish the different bass notes which makes for a much more pleasant listening experience. As other reviews have stated, I am now a JL fan for life.

Pros: Easy install Incredible sound JL quality, very well made Peace of mind knowing the box was designed for the speaker

Cons: Other than the price, which is understandable for the quality product you are getting, there are none

Nice sub

Written By Zach, Texas on Saturday, March 14, 2015

Crutchfield Customer Review (What's this?)

This is a nice setup. It hits hard and is very responsive. It sounds good with all kinds of music. I've got it hooked up to a kicker cx600.1 amp. I'm sure it will get better after tuning the amp and some break-in time. The only complaint I have is the smell of the glue and or carpet on the box. I'm sure that will go away as it airs out.

Pros: Sounds good, built well

Cons: Smell of glue/carpet.

Quality Construction and Sound

Crutchfield Customer Review (What's this?)

I tried to go the cheaper route prior to buying this subwoofer for my 08 Ram. Save yourself the hassle and just by this you will love it. I paired it with a JX500 amp and it sounds loud in clear from Country to House music.

Crutchfield Customer Review (What's this?)

Very pleased with this product. Purchased with a kicker ix 1000.5 amp along with two pair of focal iss 690's and installed them in my 13' ram sport. Great system for the limited space available in the truck. Sound is very clean from previous system I've had in previous trucks.

Pros: Great sound and use of space in limited install area.

Cons: Removal of the fold out bench under seat needs to be removed.( always has to be removed with any upgraded box)

Another top-notch quality JL Audio product

Written By JJ, Crowley, TX on Saturday, January 18, 2014

Crutchfield Customer Review (What's this?)

I had this same sub installed in my '08 Lancer when I gutted the old factory RF system out of it so I had first-hand experience that the bass was going to be nothing short of stupidly loud. With the sub itself costing 260, you're essentially paying 340 for the custom enclosure and mounting hardware, which considering how odd of an enclosure my factory 7" "sub" with the JBL system had, I probably couldn't have had one made for that much. Installation is essentially measuring 5" from the transmission hump, placing a wax piece (supplied) there, putting a (supplied) allthread in the box to make an impression on the wax, drilling an 0.5" hole where the impression was made, and securing it from the bottom - and that's it, aside of wiring an amp, of course (I used a JL XD300/1). On my '13 Ram, I didn't have to bend the heat shield like the supplied instructions say you might have. Tech support was very helpful on switching the factory DVC (dual voice coil) to SVC (single voice coil) (greys are positive, greens are negative) - I used the JL Audio XD-CLRAIC2-SW for the change-over, and yes, you'll need extra speaker wire for it. If you're worried about a hole in the firewall for amp wiring, it's about 4 inches above the top the brake pedal (you can see it from the inside of the cab). With it all said and done, you will absolutely LOVE this sub. Even with my bass on 0 on the equalizer, it hits hard, as I expected. This product just affirms why I'll be a JL customer for life

Pros: Simple to install Loud as all get-out

The Best!

Hands down the best sub! Words can't describe with how impressed I am with this sub! Will never buy anything less than a JL sub and amp ever again! I listening to a very wide range of music and it sounds amazing with it all! Keep it up JL

Pros: Very clean. Compact. Amazing sound. Durable.

Cons: None

Great Sub!!!

Crutchfield Customer Review (What's this?)

So much better than my other sub that blew (not a JL sub)! Easy install, plug and play, and boom boom, you're thumping. Great deep bass for movies and music. Love it and Crutchfield hands down has THE best customer service around!!

Pros: Easy install

Cons: None!!!

Crutchfield Customer Review (What's this?)

Great purchase but had a problem with a rattle in the box. It happens and Crutchfield was great. I called with the issue was not on placed hold and the technical adviser was professional and thorough. Got a replacement in four days.

Pros: Great sound. Deep base, no thumping and great craftsmanship.

Cons: Instructions were vague and in black in white (JL Audio issue).

great sub!

Crutchfield Customer Review (What's this?)

I am VERY happy with this sub. It hits REALLY hard and I think it rattles the truck pretty good for 1 10" in a sealed box. pushing it with 250 watts

Pros: easy install, great fit, hits hard

Cons: none

Nice Very Nice

Very nice sound!!!!! I wanted nice bass without sacrificing space and this did the trick. Paired with the JL XD 600/1 Nice Very Very nice won't be disappointed unless you are into losing you hearing with a over the top Bass system.

Pros: Great sound!! Hidden!!

Crutchfield Customer Review (What's this?)

I was looking to upgrade the bass in my 2012 ram crew cab. This stealthbox did the trick. it sounds great. I didn't expect one 10" sub to put out so much bass. I have it hooked up to the factory touch screen radio running with the jl audio XD300/1 amp. Perfect match, Sounds great.

Crutchfield Customer Review (What's this?)

I have an 06 Ram Quad cab. This is the third truck like this I've owned and I've used several different configurations. This box is the best fitting and best sounding I've used. I'm pushing it with an older 300 wt Kenwood amp and it sounds great. I can dial it down when the kids are in car seats in thd back, then crank it when its just me. The fit is the best i've seen.

Pros: Perfect fit on the passenger side. It allows me to use the storages on the drivers side.

Cons: Well...none at this point.

Exceeded Expectations

Written By Tommy, Panama City, FL on Sunday, September 18, 2011

Crutchfield Customer Review (What's this?)

I paired this sub with the JX250.1 amp and the combination sounds awesome. The sub hits harder and cleaner than the three 10W0's in my car. Installation was easy and it looks great under the seat. I chose to remove the back seat to conceal all of the wires behind the panels. I would definitely buy again.

Crutchfield Customer Review (What's this?)

Not bad for a single 10" woofer. JL really needs to make a box for the other side.. 2 10's would sound alot better! I can get it to flutter with heavy bass music..Running a Kenwood 1200 watt amp! but all in all it sounds really good.

Clear, crisp, lows and highs from a subwoofer, just what it's supposed to do...Pair this thing
with the right amp and you'll wonder why you were even considering dual anything?! I was
and now I'm completely satisfied and completely blown away. The deep rich bass and
responsiveness of this package is outstanding, not to mention it's minimal size and install. If
you want to maintain storage and have a system that thumps, get this!

Crutchfield Customer Review (What's this?)

Installed this box along with a JL Audio 250 x1 Sub amp
and (2) 1/2 farad caps.

Bass is very tight and deep for a single 10 "
It goes a lot deeper than I thought it would
without any distortion.

The enclosure fits perfectly under the rear seat.
Mounting is simple and straight forward. Drill 1 hole,,
drop it in place and tighten the mounting bolt and your done.

Buy this Sub,,,you won't be disappointed !!!

JL needs to build one for the opposite side of the truck !!!!

Product Research


Overview: JL Audio's Stealthbox subwoofer systems are designed to hide away in a specific vehicle. Please consult the Crutchfield Vehicle Selector to confirm compatibility with your vehicle.

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 W3v3-2 subwoofer is loaded in this sealed enclosure. Features of the W3v3 include:

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly 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 (VRC): The Vented Reinforcement Collar is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.
  • Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.
  • Elevated Frame Cooling: The elevated frame design of the W3v3 delivers high-velocity air flow through slots directly above the top plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
  • Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.
