About the MTX ThunderForm

Big bass, factory look

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.

Big bass, factory look

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.

Made for your 4-door Wrangler JK

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 rugged MDF enclosure with aviation-grade carpet curbs unwanted resonances from your sub, so you'll hear bass that's tight, hard-hitting, and way down low.

Mounts on the driver side rear wheel well

This MTX ThunderForm comes loaded with a premium-quality 10" Terminator subwoofer, and mounts on the driver side rear wheel well of your Jeep. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. 

Soft top installation note: When this sub is installed, your soft top will not fold flat, as it rests on the enclosure. You can buy 3" spacers and 3.5" 1/4-20 bolts with security heads to move the enclosure away from the side of the Jeep, allowing the top to lay flat.

Features

Vehicle Compatibility: This Thunderform custom-fit, amplified, pre-loaded enclosure is designed specifically to fit 2007-2016 Jeep Wrangler 4-door JK vehicles.

Note: Please refer to the Crutchfield Vehicle Selector to confirm fit for your vehicle.

Mounting Location: The enclosure mounts on top of the driver's side rear wheel well without taking up any usable interior space.

Enclosure: The Thunderform enclosure is made from durable MDF (Medium Density Fiberboard), that resists flexing and dampens resonance, and covered in aviation grade carpet.

Single 10" Terminator Subwoofer: The MTX enclosure comes loaded with single 10" MTX Terminator series subwoofer that's perfectly matched to the enclosure.

Soft Top: When a convertible soft top is installed, the top will not fold flat around the Thunderform. Instead, when folded down, the top rests on the enclosure (on the driver's side). One solution listed on MTX's web site (in addition to removing the top, rather than just folding) is purchasing 3" spacers and 3-1/2" 1/4-20 bolts with security heads from your local hardware store, thus moving the enclosure away from the side of the Jeep and allowing the convertible soft top to lay flat around the subwoofer.
