Description


JL Audio brand icon

Authorized dealer

The Ford F-150 is an American icon with impressive hauling capabilities and a spacious interior, especially in SuperCrew configurations. Unfortunately, Ford’s factory sound systems leave a lot to be desired in the low frequency department.
The JL Stealthbox for F-150 SuperCrew and SuperDuty Crew Cab trucks fills your truck with stunning sub bass output and quality, with no intrusion on cab space. Featuring an all-fiberglass, sealed enclosure design, this Stealthbox houses two of revolutionary 12TW3 thin-line subwoofers and installs neatly under the rear seat, without compromising rear seat comfort.

  • Contains two 12TW3-D8 subwoofers in a sealed enclosure
  • Compatible with select 2009-2025 vehicles from Ford
  • 800 watt power handling
  • Wired for 2 ohm mono
  • Installs under rear bench seat and requires removal of under-seat storage tray, if so equipped
  • Installation requires removal of OEM “subwoofer”, if so equipped
  • Does not affect folding or reclining of seat
  • Authorized Internet Dealer
  • 2 Year Manufacturer's Warranty

Jl Audio F150 Stealthbox (JL Audio SB-F-150-SCDBL/12TW3/BK)

My setup:

Subs : (2 12" 12TW3D-8's in 2018 F150 JL Audio Sub Box.) : powered by JL HD1200
Speakers : Front : JL C#650 2 way component ; Rear : JL C2 650 Coaxial for rear fill. : powered by JL VXI 400/4 ( using Tun software for all)

Did 2 months of research, 4-5 hours a day. Anywhere from caraudio.com senior members, every review online, numerous certified install audio shops : you name it, I did the research.

For the 1st month, I was sold on the Foxbox with 2 10" 10W3V3's that the dealer recommnded for me. After numerous delays, and great reviews on the stealthbox, I decided to pony up to get my project finished and cancel the Foxbox. One installer told me that the 12TW3's while not rated quite as high as the non shallow 10's, would outperfrom the 10's and be more crisp as well.

I am coming from 2 Rockford T Power 12's in a sedan, and this Stealthbox almost hits as hard, if not as hard. Very good SQL, especially for sliding under my rear seat and taking up no room. I am about to change out my factory radio for a Kenwood Excelon reference 1057 and that should really crank up the quality on everything.

TL;DR : this box is hands down the best option for a truck/F-150. I like quality, and I like power. I am a musician, better yet, a drummer. This thing delivers on both levels, quality and power, but give it the juice it deserves. JL recommends a 750W amp for it, I say do 1000 at least. These are power hungry and can handle it. I've barely scratched the surface with what it can do mainly because there is absolutely no need. Buy it! It's made by JL, for JL subs, for the F-150....what else do you want?

Great sounding sub box!!

This is a great sounding setup! It hits hard and plats well to a good variety of music genres. I recommend this if you have a F150 crewcab. It fits great. I carpeted mine to match the black carpet in my truck. That's the only thing I wish I came with.

Deep and hard bass make me entire bed of my truck rattle. I also have the JL Audio HD750 supplying the power.

Hits hard and clean

This thing is built very sturdy. It’s over 70 pounds. Put it in a 2018 F-150 with the B&O system. Powered it with a JL Audio HD 750/1. Need to start adding sound deadening since it rattles everything in the truck. The combination of this box, the speakers and the amp has exceeded my expectations for how hard it hits and how clean it sounds. Can’t go wrong with JL.
