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

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.

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 contains one JL Audio 13TW5v2-2 Thin-Line subwoofer in a sealed enclosure. The 13TW5v2-2 supports up to 600 watts power (RMS) and 1200 watts peak. The enclosed 13TW5v2-2 is a 2Ω single voice coil woofer.

  • Thin-Line Design: The patented thin-line woofer technology compresses the architecture of the JL Audio 13TW5v2-2 subwoofer and allows it to deliver great bass performance in the tightest space applications that are just over 2-1/2" deep. 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 box volume applications. Whereas a typical "small-box" 12-inch driver operates in well over one cubic foot, the larger 13TW5v2-2 is optimum in only 0.80 ft³ (significantly less volume than any other JL Audio 13.5-inch woofer).
  • 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 to 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 JL Audio 13TW5v2-2 subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a santoprene rubber surround for added durability, woofer excursion and bass response.
  • DMA (Dynamic Motor Analysis): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 13TW5v2-2's motor remains linear in motor force over a long excursion range, 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.
  • 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.

Installation: This Stealthbox installs under the driver's side of the rear bench seat of select 2004-2016 Ford F-250, F-350, or F-450 crew cab pickups.

Can I use this with the stock amplifier from the premium sound system 2011 F350 lariat?
tyler  May 12, 2019
1 answer
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
kristina  May 17, 2019 (Staff)
What amp would you use with this?
paulh  Dec 23, 2013
1 answer
Thanks for your question. In general you will want an amp that will supply about 600 Watts RMS at 3-ohms. For information on comparing amps I would recommend reaching out to an Advisor by phone or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget.

I have a Rockford Fosgate T1000-1bdCP, will this amp work with this stealthbox?
john  Aug 28, 2016
1 answer
Sure. But don't turn it up all the way, it's got about twice as much power as the speaker can handle.
wayne  Aug 29, 2016
Will a arc audio ks600.2 amp work on this sub?
josh  Jun 30, 2014
1 answer
I forwarded your question to an Advisor and they responded with the following: That amplifier will not work with this Stealthbox as it is only 4 ohm stable in bridged mode. The JL subwoofer runs a 3 ohm impedance If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
