Low-profile bass

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 select 2009-up Ford F-150 SuperCrew and SuperDuty Crew Cab trucks and installs under the rear seat. This Stealthbox® includes two 12" 12TW3-D8 thinline subwoofers from JL Audio and is wired for 2-ohm total impedance. You'll need to remove the under-seat storage tray and factory subwoofer (if equipped). 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.

Features

Overview: JL Audio's SB-F-150-SCDBL/12TW3/BK Stealthbox has been specifically designed to fit select 2009 and later Ford SuperCrew full size pickups. Please enter your vehicle information to confirm fit. The enclosure features two 12" 12TW3-D8 subwoofers in a custom down-firing sealed enclosure that mounts under the rear seat.

Subwoofers: The two 12" TW3-D8 thin-line subwoofers offer a combination of a shallow mounting depth and high excursion capability, producing deep powerful bass from a small enclosure. They feature a concentric tube structure built into the injection-molded mica-filled cone body. This supports the voice-coil and spider, while allowing the larger motor structure to be placed further forward in the speaker than with conventional designs. The two dual 8Ω voice-coil subwoofers are wired in parallel to present a 2Ω load on the single pair of terminals, and are capable of handling 800 watts RMS (400 watts RMS each driver).

Enclosure: The Stealthbox enclosure is made of fiberglass covered in black carpet designed to blend in with the vehicle's interior. The enclosure is designed to mount under the rear seat, 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.

Q
Could these fit with Weathertech F-150 FloorLiner?

Yes it can I meant
[ Michael  Jun 02, 2020 ]
A
Yes I can. I got the complete weather tech set for my sons truck before I got him the box.
[ Michael  Jun 02, 2020 ]
A
Yes, the floor liner stops where there is a "divet" in the flooring, which is as far forward as the box comes.
[ Benjamin  Jun 02, 2020 ]
Q
Does this box give the woofers enough room to travel?
[ Melvin  Apr 05, 2020 ]

A
I have them in a 2012 F150. The sound quality is great and theres no indication that the subs are hitting the grill. The box is made by JL so it's designed specifically for these subs so no need to worry about woofer travel issues.
[ Jeff  Apr 06, 2020 ]

Yes it does but if you are looking for something to wake your neighbors up this is not the Box for you

One of the Crutchfield experts recommended the JL Audio jx1000/1 mono amp. Works great for me! Sounds great and subs fit perfectly under my seat. https://www.crutchfield.com/p_136JX10001/JL-Audio-JX1000-1.html
[ Jeff  Feb 01, 2020 ]
A
JL AUDIO 1000/1. Nice hard hitting bass for my 2019 f250 crew cab truck.
[ Carlos  Jan 26, 2020 ]
Q
Just bought new F150 Raptor supercrew but don't see it listed- is it going to fit. Also is there a separate sub level control to go with it. Also is there space next to it under the seats for the amp like there is with the single sub box? thanks.
[ Justin  Jan 27, 2019 ]
1 answer
A
It is recommended for 2009 "and up" SuperCrew & SuperDuty Crew cabs, yes. It does not have built-in amplification so, it does not come with a level control. There are many compatible amplifiers that do offer a wired remote (either included with the amp or sold separately). There is no space provided for mounting of the amp under the rear seat. For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: https://www.crutchfield.com/support/ContactUs.aspx

What amp would be good to use with this?

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.
