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 contains one 13" TW5v2-2 subwoofer. It installs under the driver side of the rear bench seat. 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.

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.

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.

Enclosure 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.

Thin-Line Woofer: This JL Audio Stealthbox consists of one JL Audio 13TW5v2-2 Thin-Line subwoofer in a sealed enclosure. The sub can handle up to 600 watts RMS (1200 watts peak) and presents a 2-ohm load at the enclosure's speaker terminal.

  • Thin-Line Design: The patented thin-line woofer technology compresses the architecture of the 13TW5v2-2 subwoofer and allows it to deliver great bass performance in tight space applications, with as little as 2.5" depth. Central to the technology is the "concentric tube" structure that supports the oversized voice coil and the suspension attachments. This permits placing the motor of the woofer much further forward in the speaker than with conventional designs, while maintaining excellent linear excursion capability. Equally important is the fact that the 13TW5v2-2 design is optimized for extremely small enclosure volume applications. Whereas a typical small-box 12-inch driver operates in well over one ft³, the larger 13TW5v2-2 is optimized for only 0.80 ft³ (significantly less volume than other JL Audio 13.5-inch woofers).
  • Concentric Tube Suspension: The challenge in any low-profile woofer design is to permit enough mechanical clearance for the speaker to handle power and generate good output at low frequencies. JL Audio's patented solution employs a molded structure which spans over the edge of the motor system, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps JL Audio place the motor system higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.
  • Mica-Filled Polypropylene Woofer: The subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a Santoprene 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, the 13TW5v2-2's motor maintains a linear motor force over a long excursion range, and also maintains a 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.
  • Extra Large Voice Coils: To counteract the efficiency tradeoff of small box volumes, the 13TW5v2-2 is designed to handle very high power levels thanks to the use of a very large 7-inch diameter voice coil.

What is all needed to install this into the truck? Can you make a list so I can shop around for those parts

the JL Audio Stealthbox comes packaged with all of the hardware needed to mount the enclosure. You'll also need to add an amp to power the sub along with the required wiring. In the manual for the Stealthbox, JL Audio recommends using their HD750/1 mono amp: I hope that helps. My Bio:

Thank you !
[ Phang  Feb 25, 2021 ]
You'll need a line out converter like an LC2i and an amp to power the sub.
[ Thomas  Feb 25, 2021 ]
Hello, I was wondering if this amp for the 2009 fordf150 takes up the two open seats? Or if it takes up all 3 and the factory amp is needed to be removed

It takes up two seats. I have a 2015 Supercrew.
[ ALBERT  Sep 18, 2020 ]

What amp would you suggest to get the most out of this subwoofer?
[ Diego  May 10, 2016 ]

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.

You will have to remove the factory sub if you have one
[ derek  Oct 22, 2015 ]
[ derek  Oct 22, 2015 ]
Just curious what is involved with wiring one of these to a f150 without the Sony audio. Do I need an amp also?
[ Steveo  Aug 12, 2015 ]
3 answers
The only major installation difference is that you'll have to run wires from your two rear speakers to get an audio signal for your sub. With or without the Sony audio you'll still need an amp. There are some excellent online tutorials out there. Good luck!
[ CAMERON  Aug 13, 2015 ]
YEs you will need an amp
[ Bradley  Aug 12, 2015 ]
Yes I would do a hd750/1
