About the MTX Amplified ThunderForm

Massive MTX bass

Crinkled french fries, discarded receipts, old gum wrappers – you probably have everything in the hidden corners of your vehicle except great bass. MTX ThunderForm enclosures give you standout bass performance from a custom enclosure that blends right in.

Massive MTX bass

Crinkled french fries, discarded receipts, old gum wrappers – you probably have everything in the hidden corners of your vehicle except great bass. MTX ThunderForm enclosures give you standout bass performance from a custom enclosure that blends right in.

Designed for your 4-door Wrangler JK

MTX engineers evaluate the "sonic signatures" of top-selling vehicles like the Wrangler so they can design ThunderForms to match the interior acoustics. This ThunderForm blends inconspicuously into your truck (it fits on the driver side rear wheel well), so you get great bass without losing any space. The rugged enclosure is made from MDF with aviation-grade carpet covering to curb resonances, and the airtight enclosure provides the correct internal volume for optimal bass response. You'll get hard-hitting bass from a sub that's tough enough for Jeep duty.

The amp's built-in

This amplified ThunderForm comes equipped with a 10" Terminator sub and a cool-running 250-watt amp that provides optimal power without straining your vehicle's electrical system. A variety of inputs allow easy integration into your vehicle's sound system, and the included 20' power harness makes it a lot easier to get power to the amp.

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 and amplifier.

Class D Amplifier: The enclosure contains a built-in 250-watt Class D (digital) amplifier that allows RCA or speaker-level input. The amplifier is highly efficient and designed specifically for use with the subwoofer in the enclosure.

Built-in Low-pass Filter: The low-pass filter frequency can be varied from 50 to 150 Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.

Electronic Bass Control: The MTX Thunderform's connection panel includes a port for an optional EBC module (Electronic Bass Control - not included) that allows you to adjust the bass level from anywhere in the vehicle.

Auto Turn-On Feature: When the speaker level inputs are used, the system will automatically turn on and off with the radio.

Note: The auto turn-on feature does not operate when the preamp level inputs are used, unless the remote turn-on lead is connected.

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.
