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 black MTX ThunderForm comes loaded with a premium-quality 10" Terminator speaker and replaces the rear passenger side factory net pocket in the 1997-2002 Ford Expedition and 1998-2002 Lincoln Navigator. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. Installation hardware and a grille are supplied. The enclosure is not visible behind the grille. For the ultimate in Thundering bass, drive one with an MTX Thunder amp.
