About the MTX Vehicle-specific 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 a speaker — you install your favorite 12" subwoofer. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 0.94 cubic feet. The enclosure mounts under the driver's side rear seat of select 2004-08 Ford F-150 SuperCrew and SuperCab pickups. The seat still folds up and down, and 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.

Customer Q&A

1 question already asked

Q
Does this fit a full size 12 or just shallow mount?
[ brandon  Sep 28, 2017 ]
1 answer
A
Just a shallow mount. Also, the sub will sit down into the box a little so make sure the outer ring (where you put the screws) is not too large in diameter so it will sit down in this inset.
