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 2005-up Nissan Xterra SUVs. It installs in the passenger side rear cargo area. This Stealthbox® includes one 12" 2-ohm W3v3 subwoofer from JL Audio. The included steel-mesh grille protects the sub. 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.

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.

Great bass without losing precious cargo space

Crutchfield Customer Review (What's this?)

Most reviews I read on this stealthbox said that it's expensive, but you get what you pay for. That's exactly the way I would describe it. The sound is great, and it fits perfectly into the side of the cargo area of my 2013 Xterra, allowing me to fully utilize all of the space in the back.

Pros: Great sound and secure mount out of the way

Cons: High price, but worth it

Crutchfield Customer Review (What's this?)

The box fits perfect into the designed space. It came packaged in a custom fit foam enclosure. That was awesome to see as it is a long trip from the East Coast to Alaska.

Pros: I love the way my mirrors vibrate to the beat! Installation was easy as the instructions described.

Cons: Running the wires was a Pain!

Crutchfield Customer Review (What's this?)

If you have a second gen Xterra, you need this enclosure!! Sure it's pricey, but you get what you pay for. Installed this sub takes up hardly any room, and sounds great!! Sound quality and volume are both outstanding, plus with all the extra room I'll no longer need to take a tent camping.

Pros: looks, quality, sound

Cons: Price, but again, you get what you pay for.

excellent on all fronts

Crutchfield Customer Review (What's this?)

this is the real deal. installed on a 2011 xterra, and the fit is perfect, the sound is incredible. installation was fairly easy, but the instructions leave a bit to be desired. what's the spacer for? why not include a rubber grommet instead of recommending silicone? a recommendation on speaker wire routing would've been nice too. all in all though, the quality of this product is great. if you want great sound in your xterra, this is a no-brainier.

Pros: sound, perfect fit

Cons: instructions

What a great purchase! I have been a fan and end user of JL Audio
subwoofers for several years. As time has progressed I found myself
wanting a vehicle to hold more than just a gallon of milk around my
system. This box does not disappoint me in clarity, loudness or space
needed for the enclosure. This Stealthbox provides crystal clean sub bass
that easily fills the entire cabin (and then some) AND leaves me with ample
room to go camping as well. I HIGHLY recommend this to anyone with an

Product Research


Overview: JL Audio's Stealthbox subwoofer systems are designed to hide away in a specific vehicle. Please consult "Outfit My Car" 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 12" JL Audio W3v3-2 subwoofer is loaded in this sealed enclosure and wired as a 2Ω load at the enclosure's speaker terminal.

  • 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.
