About the MTX Amplified ThunderForms

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.

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 houses a Terminator 10" woofer and a cool-running 200-watt amp that's custom designed to provide optimal power without straining your vehicle's electrical system. The enclosure fits behind the rear seat in your 2000-06 Chevy 1500 or GMC Sierra Crew Cab, and MTX includes the hardware for relocating your jack. 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.

Features

Vehicle Compatibility: This MTX ThunderForm custom-fit, amplified, loaded enclosure is designed specifically to fit the 2000-2006 Chevrolet 1500 Crew Cab Truck

Note: Please refer to the Crutchfield Vehicle Selector to confirm fit for your vehicle.

Mounting Location: The ThunderForm amplified, loaded enclosure mounts behind the rear seat of your 2000-2006 Chevrolet 1500 Crew Cab Truck (install hardware supplied). Your vehicle's jack will need to be relocated.

Molded Enclosure: The molded, high-density polyethylene resin enclosure resists flexing and dampens resonance.

10" Terminator Subwoofer: This enclosure comes loaded with a single 10" MTX Terminator woofer. The woofer has an unusual impedance, specifically designed with 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.

Tools Required For Installation:

  • Powered screwdriver
  • 6" Bit holder extension
  • 17mm Socket
  • #2 Phillips head bit
  • 10mm Socket
  • Socket wrench
