Subwoofer Enclosures

Thunderforms are a line of vehicle specific enclosures produced by MTX Audio. Each enclosure is designed to fit perfectly within a specific vehicle make, model and/or year to maximize the use of the available space in a compatible vehicle. These enclosures are identical to Bass Slammer enclosures but are loaded with MTX Thunder series component subwoofers. Some Thunderforms also include an amplifier to further simplify the installation process.
