Benefitting from our revolutionary thin-woofer technology, this Stealthbox® for F-150 SuperCab and SuperDuty SuperCab trucks is designed to install neatly under the rear seat with no intrusion on cab space. Featuring an all-fiberglass, sealed enclosure design, our Stealthbox® houses a 10-inch TW3 thin-line subwoofer and fills your truck with loads of deep bass output. Seat folding and reclining are unaffected, and we’ve even incorporated a recess on the Stealthbox’s top for mounting an amplifier, if desired.
