About the MTX ThunderForm Unloaded Enclosure
Crinkled french fries, discarded receipts, old gum wrappers you probably have everything in the hidden corners of your vehicle except great bass. ThunderForm enclosures fill the nooks and crannies of your vehicle with low tones that stand out, but their factory look blends right in.
MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. Each ThunderForm fits and blends inconspicuously into your vehicle, so you get great bass without losing any space. They're made of high-density polyethylene resin to curb resonances they deliver bass that's tight, hard-hitting, and way down low. The airtight enclosure provides the correct internal volume to yield optimum bass response.
This black enclosure comes without a speaker you install your favorite 10" subwoofer. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 1.0 cubic foot. The enclosure mounts under the rear seat of select 2007-up Chevrolet Silverado or GMC Sierra Crew Cab pickups.

Well built box that sounds good with a Kicker speaker. Does require you to bolt it to the floor for proper installation.
