About the MTX C1500C-07L ThunderForm

Massive MTX bass 

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.

Massive MTX bass 

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.

Designed for your Chevy Silverado or GMC Sierra 

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. The MDF enclosure with its aviation-grade carpet covering curbs unwanted resonances from your sub, so you'll hear bass that's tight, hard-hitting, and way down low.

Don't lose any space

This rugged MTX ThunderForm comes loaded with a premium-quality 10" Terminator subwoofer, and mounts under the rear seat of your Chevrolet Silverado or GMC Sierra Crew Cab. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer.
