Overview

Our take on 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 charcoal enclosure comes without speakers — you install two of your favorite 10" subwoofers. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 0.815 cubic feet. The enclosure mounts under the rear bench seat of select 2004-up Nissan Titan King and Crew Cab pickups. Your jack stays in its factory location.

Great fit, great sound.

2012 Nissan Titan
Crutchfield Customer Review (What's this?)

This product did fit well within my truck, but did not play nice with the JL10W3 subs that I purchased. I had to build two spacers to make it work. Also, the color listed as charcoal and listed as matching the interior of my truck did not match at all. All in all, a fine product that sounds nice and fits perfectly within my truck.

Pros: Fit my truck well. Sounds great but that's probably more to do with the quality speakers I installed.

Cons: Color is way off/ doesn't match. The speakers I purchased didn't fit, so I had to build spacers. Wish it was ported somehow.
