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.

JL Audio Stealthbox installed

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 2011-up Volkswagen Jetta Sedan models. It installs in the driver's side corner of trunk. This Stealthbox® includes one W1v3 10" 2-ohm subwoofer from JL Audio.

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.

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 10" JL Audio W1v3, 2Ω subwoofer is loaded in this sealed enclosure.

  • Surround Stress Relief: By creating a radius 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.
  • Interlocking Cone & Dust Cap: The W1v3's utilize a dust cap that is not just glued, but also interlocks with features molded into the cone body for a tight snap-fit. This creates a more rigid cone assembly and a more reliable dust cap attachment.
  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W1v3 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: 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 greatly reduces failures due to glue breakdown or material weakness. It does this by greatly 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. This reduces thermal compression effects and enhances reliability
  • Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v3 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. This type of assembly ensures precise lead wire length, lead wire entry and exit angles; and coil to spider perpendicularity.
  • 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 of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

Will this fit the Jetta Sportwagen?
[ Tim  Jan 22, 2023 ]
1 answer
Greetings Tim, and thank you for your question. This JL Stealthbox is for the sedan only. I checked 2009-2014 Sportwagens for a custom fit subwoofer, and unfortunately Crutchfield does not have anything at this time
[ Thomas  Jan 22, 2023 ]  Staff
will this fit a 2017 jetta tsi sport?

Honestly I wouldn't know I only just received all my order and haven't yet installed it in my 2015 tsi .
[ CEDRIC  Nov 13, 2020 ]
Will this fit the 2019? (GLI 35th anniversary edition)
[ Kyle.S  Sep 12, 2019 ]
1 answer
Hi Kyle! Thanks for your question! Unfortunately we do not have any vehicle research info on file for the 2019 Jetta's at this time. We do add those as we are able to gain access to one to complete our research, but we have not had the opportunity for that. Feel free to keep a check back with us in the future, hopefully we will be able to have more info on that soon.
[ JESSICA  Sep 23, 2019 ]  Staff
Will this fit on both sides of the trunk? i.e. - 2 boxes?
[ COLTON  Aug 24, 2018 ]
1 answer
No. It's made to fit the driver's side only.
[ Ryan  Aug 29, 2018 ]  Staff
What would be a good amp to buy for this custom JL audio subwoofer ?
[ NEAMUL  Sep 11, 2017 ]
2 answers
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.

JL Audio Jx500/1d Mono Subwoofer Amplifier - 500 Watts RMS X 1 At 2 Ohms
[ Nathan  Sep 11, 2017 ]
What is the interior volume of this enclosure?
[ Neil  May 13, 2016 ]
1 answer
We do not have that information, but we can make an educated guess on it. JL Audio makes these Stealthboxes specifically for the subwoofer in them. They put a 10W1v3-2 into it and its a sealed box. They also recommend 0.55 cubic feet sealed box volume for that subwoofer which leads me to believe the box has 0.55 cubic feet internal volume. I hope that helps! My Bio:
