MTX ThunderForms

Overview

Our take on the 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.

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 molded MTX ThunderForm comes loaded with a premium-quality 10" Terminator speaker and mounts under the rear seat on the driver side of the 1988-2006 GM/Chevrolet Extra Cab truck, with the woofer firing downward. It bolts to the floor of the vehicle. There is no loss of leg room and the factory jack kit is not disturbed. 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.
