JL Audio SB-F-150-SCDBL/12TW3/BK
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 an all-fiberglass, 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.
JL Audio 12TW3-D8
TW3 12-inch Subwoofer Driver (400 W, dual 8 Ω voice coils)
Building on the core technology of our TW5 thin-line subwoofers, the new TW3’s deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3’s.
To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs.
TW3’s are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know you’re going to love working with these amazing subwoofer drivers.
Deep, powerful and accurate JL Audio bass is now possible in more applications than ever.
- Very shallow mounting depth (3.25 / 3.50 Inches)
- No pole vent: permits mounting close to rear wall of enclosure.
