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 black enclosure comes without a speaker — you install your favorite 10" subwoofer. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 0.6 cubic feet. The enclosure mounts inside the factory center console in select 2007-up Chevy Suburban, Chevy Tahoe, and GMC Yukon (must have front bucket seats). It will not fit in trucks with AC vents on the back of the center console or in vehicles with a deep storage area in front of cup holders.

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.

Not exactly a perfect fit

Written by: Lujo from Massachusetts on October 4, 2015

Crutchfield Customer Review (What's this?)

This product did the job, however it does NOT fit the 09 GMC Yukon perfectly as claimed. I had this professionally installed and it took the technicians hours to customize the fit. There were adjustments that had to be made to make the product fit properly. I watched the installation being done so I know for a fact this was the issue. Also the instructions were awful.

Pros: Once finally installed the product served its purpose.

Cons: The customized fit was far from customized. The instructions were horrible.

Warranty

5 Year Warranty Terms: This product carries a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.
