About: JL Audio Stealthbox Dual 12" 800W RMS TW3 Subwoofers for 2009-Up Ford F-150 SuperCrew / 2017-Up SuperDuty Crew Cab 

Stealthbox® for 2009-Up Ford F-150 SuperCrew / 2017-Up SuperDuty Crew Cab

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.

Our 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 a sealed enclosure design, this Stealthbox® houses two of our revolutionary 12TW3 thin-line subwoofers and installs neatly under the rear seat, without compromising rear seat comfort.

The Hard Data: Contains two 12TW3-D8 subwoofers in a sealed enclosure. 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.

Specifications:

  • Sealed fiberglass enclosure
  • Installs under the rear seat
  • 400 Watts Each / 800 Watts Total RMS power handling (1600 watts peak power total)
  • 2-ohm total impedance
  • Requires removal of under-seat storage tray and factory sub (if present)

What's in the Box:

  • Custom subwoofer enclosure loaded with two 12" TW3-D8 thinline subwoofers
  • Mounting hardware
  • Installation instructions
