Our take on the MTX ThunderForms by Crutchfield's Jo Greene
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 ThunderForm fits under the rear seat of your 2007-up Chevy Silverado Crew Cab pickup. The enclosure houses a rugged Terminator subwoofer its strong, light cone and special suspension design ensure high output and low distortion.
