Our take on the MTX Amplified ThunderForms by Crutchfield's Jo Greene
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. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers.
This MTX ThunderForm comes loaded with a premium-quality 10" Terminator subwoofer and a specially-designed amp that puts out 200 watts of power. It replaces the console in in the following vehicles: 1992-00 Chevrolet Suburban, 1992-99 GMC Yukon, 1995-00 Chevrolet Tahoe, 1999-00 Cadillac Escalade, and 1992-94 full-size Chevrolet Blazer.

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to replace the factory console in select 1992-2000 Cadillac, Chevrolet, and GMC Escalade, Suburban, Yukon, Tahoe, and full-size Blazer models. Please refer to the Crutchfield Car Selector to confirm fit for your vehicle.
Enclosure: The ThunderForm enclosure is made of molded high-density polyethylene resin, which dampens resonance and is rigid enough to resist flexing. The color of the enclosure matches factory GM colors. Three cup holders (2 for the front and 1 for the rear) and a tray are molded into the top of the enclosure. It is a down-firing acoustic suspension (sealed) chamber.
Mounting Location: This enclosure is designed and molded to mount between the front bucket seats, replacing the factory console, with the woofer firing downward. Note: The provided dimensions are taken at the widest points of the enclosure. Keep in mind that these enclosures are custom made to fit in this particular vehicle, so the enclosure will fit properly in only one specific location. Mounting hardware is included to bolt the enclosure to the floor of the truck.
10" Terminator Subwoofer: This enclosure comes loaded with a single 10" MTX Terminator woofer. The woofer has an unusual impedance, specifically designed for the built-in amp, and cannot be replaced with a standard MTX model.
Class D Amplifier: The enclosure contains a built-in 200-watt Class D (digital) amplifier that allows RCA or speaker-level input. The amplifier is highly efficient and designed specifically for use with the subwoofer in the enclosure.
Electronic Bass Control (EBC): The EBC is a wired remote and allows you to adjust the bass level from anywhere in the vehicle. Installing the EBC is optional.
Low-pass Crossover: The low-pass crossover point is adjustable from 50 to 150 Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.
- Gain Control: rotary control; set the gain of the amplifier is match the input
- Crossover Control: rotary control; adjust the crossover from 50 to 150 Hz
