DESC: 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. MTX Audio engineers measure top-selling vehicles and evaluated their sonic signatures. Using unique materials and creative manufacturing processes, MTX develops enclosures that deliver high quality sonic performance, yet fit in the wasted space where you can't fit anything else. ThunderForm vehicle-specific subwoofer enclosures are designed to fill your car's deepest, darkest corners and deliver mother-loads of bass. ThunderForm enclosures are engineered to deliver high SPL with very low distortion. They match the interior shape of your particular vehicle so you won't have to compromise cosmetic integrity. This is especially nice for those with leased vehicles who want to enjoy added bass without the hassle of messy installations.
