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 in select 2007-up General Motors crew cab trucks under the rear seat bench. This Stealthbox® includes two 12" TW3-D8 thinline subwoofers from JL Audio, wired for 2-ohm total impedance. 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.

Product Research

Features

Overview: JL Audio's SB-GM-SLVCC2/12TW3/BK Stealthbox has been specifically designed to fit select 2007 - 2013 Chevrolet Silverado and GMC Sierra Crew Cab trucks with an ebony interior. It features two 12" 12TW3-D8 subwoofers in a custom down-firing sealed enclosure that mounts underneath the rear seats.

Subwoofers: The JL Audio Stealthbox's two 12" 12TW3-D8 subwoofers offer a powerful combination of a shallow mounting depth and high excursion capability, producing deep powerful bass from a small enclosure. The two dual 8 ohm voice-coil subwoofers are wired for a 2 ohm output to a single set of terminals, and are capable of handling 800 watts RMS (400W RMS each driver).

Enclosure: The Stealthbox enclosure is made of fiberglass coated in black carpet designed to blend in with the vehicle's interior. The enclosure has been configured to mount under the rear seats, so no usable cargo or passenger space is taken up. The enclosure will not effect the folding of the rear seats or passenger's leg room.

Note: This Stealthbox will not fit "Classic" model vehicles.

Q
What size speaker wire from amp to box is recommended? I will be running the 750/1HD. Thanks
[ Ron  Jul 23, 2021 ]
1 answer
A
If you are mounting that amp to the box as shown in the manual, then 12 gauge speaker wire is recommended. If the amp will be mounted further away from the box, then we recommend contacting an advisor by calling 1-800-324-9695 to discuss this in greater detail to check if bigger wire is needed.

Thanks for your question. For information on selecting the best amp 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.
