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 two premium-quality 10" Thunder4500 speakers and mounts behind the seat of the 1997-up Ford F-150 or 1997-00 F-250 Light Duty regular cab truck, with no loss of leg room. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers.

The enclosure has one set of speaker terminals and the two woofers are wired for a 4-ohm total impedance. Installation hardware is supplied. For the ultimate in Thundering bass, drive one with an MTX Thunder amp.
