You can't drive 55, and you can't rely on your stock speaker system to pump out bone-shaking bass. But dropping a bass tube or universal sub enclosure in the back of your ride bites into cargo capacity and leg room. With a custom MTX Audio ThunderForm Subwoofer Enclosure, you can dial up the decibels without sacrificing storage. They're designed to fit behind seats, against trunk walls and in other out-of-the-way locations, filling dead space with dope bass.
Blending in like a (karma) chameleon, it's hard to tell where your factory trim ends and your MTX Audio ThunderForm begins. They're built from premium polyethylene resins, medium-density fiberboard (MDF) or fiberglass and available in a range of factory style colors. And since the hue is molded all the way through, scuffs and scratches don't stick out like sore thumbs.
Whether you're looking for an out-of-the-box boomer or a blank slate, there's an MTX ThunderForm Subwoofer Box for every taste. Loaded ThunderForms come with punchy subs while Amplified ThunderForms sport an amplifier and subwoofer. Or, you can get an Unloaded MTX Thunder Form and fill it with your favorite bass pusher. Whichever route you choose, you're covered by a 2-year warranty.
