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
This Stealthbox® enclosure fits 2001-12 Ford Escape and 2001-11 Mazda Tribute models, plus the 2005-11 Mercury Mariner. It installs against the driver side wheel well in the cargo area. This Stealthbox® includes one 10" 2-ohm W1v3-2 subwoofer from JL Audio. A steel-mesh grille is included to protect the sub. 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.

Important Note: The Stealthbox® will not fit in Hybrid models.

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 compatibility.

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: A 10" JL Audio W1v3-2 subwoofer is loaded in this enclosure and features an injection-molded, mica-filled polypropylene cone with an embossed metallic JL Audio logo and a rubber surround for added durability, woofer excursion and bass response.

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, W1v3 motors remain linear in motor force over a long range of excursion, and also maintain 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 the 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. This reduces thermal compression effects and enhances reliability.
  • Elevated Frame Cooling System: The elevated frame design of the W1v3 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.

Can this box be installed without having to previously had the factory subwoofer in it? My vehicle came without a subwoofer and I'm checking to make sure that this will go in that space

It's likely you can use it without having had one but to verify that please give us a call at 800.324.9695 to speak with one of our advisors so we can get your exact year, make, and model to confirm it will work.
[ Arielle  Sep 22, 2022 ]  Staff
It is possible to install without an amp?
[ Pedro  Apr 21, 2021 ]
1 answer
This is an unpowered subwoofer box which requires an amp to also be installed with it.
[ Paul  May 09, 2021 ]  Staff
I have a 2020 outlander sport, will this fit?
[ charles  Oct 06, 2020 ]
1 answer
This box is not rated as fitting it. I checked JL Audio's complete list of Stealthboxes only to find they do not currently make one for your vehicle and we don't have one from any other manufacturer either. This may change over time and we have advisors that can be reached by calling 1-800-324-9695 to check for possible options then.
[ Paul  Oct 27, 2020 ]  Staff
Does this only come in one color? Can the box be made in black to match my darker interior?
[ Richard  Oct 05, 2020 ]
1 answer
I've checked on JL's site only to find there is only one color this box comes in. I wish I had different news for you there.
[ Paul  Oct 24, 2020 ]  Staff
is there one for the other side?
[ james  Sep 11, 2020 ]
1 answer
Not for this vehicle. I asked the same question!!
[ ANDRE  Sep 11, 2020 ]
What does this come with?
[ Michael  Mar 30, 2019 ]
1 answer
It comes with the sealed fiberglass enclosure pre-loaded with a single JL W1v3-2 10" 2-ohm subwoofer. It installs in the driver side wheel well of cargo area. It also includes a steel mesh grille and some mounting accessories. You will still need to pair it with an amp. If you have questions about matching an amp or what you'll need to install you can reach one of our friendly Product Advisors here:
[ Cosmo  Apr 14, 2019 ]  Staff
is this powered or do i need an amp too?
[ bigtrout  Mar 22, 2019 ]
1 answer
It is not powered. You will need to get an amp with it. We have advisors that you can reach by calling 1-800-324-9695 who can discuss your goals and preferences to give you a recommendation on an amp for it My Bio:
