About the MTX Amplified ThunderForm
Massive MTX bass
Massive MTX bass
Crinkled french fries, discarded receipts, old gum wrappers – you probably have everything in the hidden corners of your vehicle except great bass. MTX ThunderForm enclosures give you standout bass performance from a custom enclosure that blends right in.
Designed for your Chevy Silverado or GMC Sierra
MTX engineers evaluate the "sonic signatures" of top-selling vehicles like the Silverado and Sierra so they can design ThunderForms to match the interior acoustics. This ThunderForm blends inconspicuously into your truck (it fits under the driver side rear seat), so you get great bass without losing any space. The rugged enclosure is made from medium-density fiberboard covered in aviation-grade carpet, and the airtight enclosure provides the correct internal volume for optimal bass response. You'll get hard-hitting bass from a sub that's tough enough for truck duty.
The amp's built-in
This amplified ThunderForm comes equipped with a 10" Terminator sub and a cool-running 250-watt amp that provides optimal power without straining your vehicle's electrical system. A variety of inputs allow easy integration into your vehicle's sound system, and the included 20' power harness makes it a lot easier to get power to the amp.

More details on the MTX Amplified ThunderForm
Vehicle Compatibility: This ThunderForm custom-fit, amplified, pre-loaded enclosure is designed specifically to fit 2007-2015 Chevrolet Silverado and GMC Sierra 1500/2500 Double Cab pickup trucks.
Mounting Location: The enclosure mounts under the driver's side rear seat without taking up any usable interior space.
Enclosure: The Thunderform enclosure is made from durable MDF (Medium Density Fiberboard), that resists flexing and dampens resonance, and covered in aviation grade carpet.
Single 10" Terminator Subwoofer: The MTX enclosure comes loaded with single 10" MTX Terminator series subwoofer that's perfectly matched to the enclosure and amplifier.
Class D Amplifier: The enclosure contains a built-in 250-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.
Electronic Bass Control: The MTX Thunderform's connection panel includes a port for an optional EBC module (Electronic Bass Control - not included) that 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.
