Description
The SMS Precision Ford F-150 Underseat Subwoofer Enclosure Builder is a built-to-order enclosure for compatible 2009-and-newer F-150 crew-cab trucks. The current live configuration requires a 2.5-inch rear-seat lift and allows the enclosure to be matched to the selected subwoofer layout, finish and amplifier plan.
Available layouts include two or four 8-inch subwoofers, two 10-inch subwoofers, or two, four or six 6.5-inch subwoofers. Final airspace, cutouts, mounting depth, port design and enclosure dimensions are verified for the chosen drivers and truck before fabrication.
