About the MTX ThunderForm

John Pollard
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. The high-density polyethylene resin enclosure curbs unwanted resonances from your sub, so you'll hear bass that's tight, hard-hitting, and way down low.

This molded MTX ThunderForm comes loaded with a premium-quality 12" Terminator subwoofer, and mounts in the trunk on the passenger side of your 2005-up Ford Mustang coupe ( will not fit in the Mustang convertible). The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. For the ultimate in thundering bass, drive one with an MTX Thunder amplifier.

Features

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select 2005-2012 Ford Mustang coupes (it's not compatible with the convertibles). Please refer to the Crutchfield Car Selector to confirm fit for your vehicle.

Mounting Location: This enclosure is designed to mount in the trunk, on the passenger's side. Note: The provided dimensions are taken at the widest points of the enclosure. Keep in mind that these enclosures are custom made to fit in this particular vehicle, so the enclosure will fit properly in only one specific location.

Woofers: The ThunderForm enclosure is loaded with one 4Ω, 12" MTX Terminator subwoofer.

Tools Required: The manual provides this list of required tools:

  • Powered Screwdriver
  • #2 Phillips Head Bit
  • 6" Bit Extension
  • 10mm Wrench
  • 5/16" Wrench
