ThunderForm Vehicle-Specific Enclosures
Every car or truck has wasted space. You know, the places behind or beneath the seats where loose change and french fries hide. Those spaces are cryin' for bass. MTX Audio responds with ThunderForm vehicle-specific subwoofer enclosures.

Including Spec Sheets, Install Guides, Installation Video and more!
Matching Colors, Cool CosmeticsThey're available in a variety of colors to match the interior of your particular vehicle and so you don't have to compromise its cosmetic integrity. This is especially nice for those who lease their vehicles and want to enjoy added bass without the added hassle of messy installations.
High Performance MaterialThe material in ThunderForm enclosures is a high density polyethylene resin, which is resilient enough to transform into various shapes, yet rigid enough to avoid flexing. It also has enough density to dampen any resonance (No cabinet "ping" allowed).
WarrantyLoaded ThunderForm models are protected by MTX Audio's 2 year limited warranty. Amplified ThunderForm models are covered by our 1 year limited warranty. Contact MTX Audio for details.
Available OPTIONS May Be Purchased Below. Options Include Upgraded Woofers, External Amplifiers, and MTX's Exclusive Internal Built-In Amp, As Described in the Next Section:
AMPLIFIED Models: A Totally New Concept in Materials, Design and Manufacturing On amplified ThunderForm models, we've added an on-board, 200-watt, Class-D amplifier. The amp is highly efficient, and has been designed specifically for the subwoofer in the enclosure. You get deep, low bass, without having to wire in a separate amplifier. MTX Audio's "Smart-Engage" Circuitry (patent pending) eliminates the need to remove your factory head-unit during most installations (now, if you don't know how much time that feature alone will save you, just go sit in your car, and imagine having to tear out the whole dash... and really hope you don't snap any of the clips in there).

Amplified ThunderForm models feature a proprietary woofer design utilizing a .35 ohm for single woofer, (.7 ohm in parallel for dual woofer), long excursion voice coil. This design takes full advantage of the efficiency of Class D amplifier design while delivering powerful, low frequency extension. Add all of these features up, along with over voltage, over current, and voice coil short protection, and you have a unit that looks and operates like it came as an original part of the vehicle. The included wiring kit contains a 20' power harness, gold plated power and ground ring terminals, and a custom-tooled MTX Audio fuse holder.
Amplified Features - Highly efficient, on-board, rugged, 200 watt Class-D amplifier
- Unique, custom-designed subwoofer complements the efficiency of the Class-D amplifier to deliver deep, low bass
- "Electronic Bass Control" (EBC) so the bass level can be adjusted from the driver's seat.
- Line Level and Speaker inputs with "Smart-Engage"
