MTX vehicle-specific unloaded enclosures preserve all the legroom in pickup trucks and all the cargo space in SUVs. Each enclosure is an acoustically-designed, non-resonant, airtight enclosure, with the correct internal volume to yield optimum bass response from a compatible subwoofer.

So what makes these enclosures different than a standard sub box? MTX designs each enclosure for optimum performance in your specific vehicle's acoustic space. Using state-of-the-art rotational molding techniques, and exotic high-density polyethylene, MTX creates a sculpted masterpiece of a sub box, beautifully finished to blend with your interior. And they sound as good as they look, delivering bass that's tight, accurate, hard-hitting, and way down low.

This enclosure comes without a speaker — you install your favorite 12" Type 1 subwoofer. For best results, Bass Slammer strongly recommends using a speaker designed for an enclosure with a volume of between 0.5 and 1.0 cubic feet. The enclosure mounts under the rear side seat on the driver's side of the 2004-up Ford F-150 Crew Cab truck.
