About the MTX Amplified ThunderForm

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.

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.

Will this system plug into the stock receiver on a 2015 Chevy Silverado or would the receiver need to be replaced with something compatible?

Hi Cliff, thank you for your question. It looks as though this question has already been answered, but just to confirm, yes, the MTX-Amplified Thunderform will fit under the driver side rear seat of the 2013 Silverado Ext. Cab. Chat with an Advisor online or by phone at 1-800-324-9695. They'll be happy to answer any additional questions you may have!

It fits right under the driver side rear seat. You'll have to drill holes to mount it properly.
