MTX Amplified ThunderForms
Custom-fit powered subwoofer for 2000-06 Ford F-250 Super Duty / F-350 regular cab (Black)
Our take on the MTX Amplified ThunderFormsby Crutchfield's John Pollard
Crinkled french fries, discarded receipts, old gum wrappers you probably have everything in the hidden corners of your vehicle except great bass. ThunderForm enclosures fill the nooks and crannies of your vehicle with low tones that stand out, but their factory look blends right in.
MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. Each ThunderForm fits and blends inconspicuously into your vehicle, so you get great bass without losing any space. They're made of high-density polyethylene resin to curb resonances they deliver bass that's tight, hard-hitting, and way down low. The airtight enclosure provides the correct internal volume to yield optimum bass response.
This amplified ThunderForm comes equipped with a cool-running 200-watt amp that's custom designed to provide optimal power without straining your vehicle's electrical system. The enclosure replaces the rear passenger net pocket. MTX's Electronic Bass Control (EBC) lets you adjust the bass level from the driver's seat. A variety of inputs allow easy integration into your vehicle's sound system, and the included 20' power harness simplifies supplying power to the amp.

Molded Enclosure: The molded, high-density polyethylene resin enclosure resists flexing and dampens resonance.
Dual 10" Terminator Subwoofers: This enclosure comes loaded with dual 10" MTX Terminator woofers. The woofers have an unusual impedance, specifically designed for the 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.
Built-in Low-pass Filter: The low-pass filter frequency can be varied from 50 to 150 Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.
External Bass Control: The external bass control allows you to adjust the bass level from anywhere in the vehicle.
Auto Turn-On Feature: When the speaker level inputs are used, the system will automatically turn on and off with the radio.
Note: The auto turn-on feature does not operate when the preamp level inputs are used, unless the remote turn-on lead is connected.
