Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. ThunderForm enclosures fill the nooks and crannies of your vehicle with low tones that stand out, but their factory look blends right in.

MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. Each ThunderForm fits and blends inconspicuously into your vehicle, so you get great bass without losing any space. They're made of high-density polyethylene resin to curb resonances — they deliver bass that's tight, hard-hitting, and way down low. The airtight enclosure provides the correct internal volume to yield optimum bass response.

This molded MTX ThunderForm comes loaded with a premium-quality 12" Thunder4500 subwoofer modified especially for amplified Thunderforms, with a specially-designed amp that puts out 200 watts of power. It installs in your 2005-up Ford Mustang in the passenger side of the trunk. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers. Hardware is included.
