About the MTX ThunderForm Unloaded Enclosure

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.

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 enclosure comes without speakers — you install two of your favorite 12" subwoofers. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 1.25 cubic feet. The enclosure mounts behind the seat of select 2004-up Ford F-150 Regular Cab pickups. The jack stays in its factory location.

Please check with us before purchasing by using the vehicle selector on our site, or calling an Advisor at 1-888-955-6000 to verify fit information.

1 question already asked

Q
Is this box vented or closed? And are there 2 separate chambers for the subs, or do they share air?
