MTX ThunderForms

Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. But with custom ThunderForm enclosures, you can fill the nooks and crannies of your car, truck, or SUV with low tones that stand out.

MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. With "rotational molding," MTX ensures that each ThunderForm fits and blends inconspicuously into your vehicle. They're made of high-density polyethylene resin to curb resonances and deliver bass that's tight, hard-hitting, and way down low.

This black MTX ThunderForm comes loaded with a premium-quality 10" Terminator speaker and mounts in the trunk on the passenger's side of the 1998-up Volkswagen Beetle. You'll keep your cargo space and the trunk light is still functional. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. Hardware is included. For the ultimate in Thundering bass, drive one with an MTX Thunder amplifier.
