About the MTX Amplified ThunderForm

Jo Greene
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 10" Terminator subwoofer and a specially-designed amp that puts out 200 watts RMS of power. It installs under the rear seat of your 2009-up Ford F-150 SuperCab or SuperCrew, with no loss of leg room. MTX's Electronic Bass Control (EBC) lets you adjust the bass level from the driver's seat. Hardware and harness are included.

Features

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select Ford F-150 SuperCab models. Please refer to the Crutchfield Car Selector to confirm fit for your vehicle.

Enclosure: The ThunderForm enclosure is made of molded high-density polyethylene resin, which dampens resonance and is rigid enough to resist flexing. It is an acoustic suspension (sealed) chamber.

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

10" Terminator Subwoofer: This enclosure comes loaded with one 10" MTX Terminator subwoofer. The woofer has an unusual impedance, specifically designed for the built-in amp, and cannot be replaced with standard MTX models.

Class D Amplifier: The enclosure contains a built-in 200-watt Class D (digital) amplifier that allows RCA or speaker-level input. The amplifier is highly efficient and designed specifically for use with the subwoofers in the enclosure.

Electronic Bass Control (EBC): The EBC is a wired remote and allows you to adjust the bass level from anywhere in the vehicle. Installing the EBC is optional.

Low-pass Crossover: The low-pass crossover point is adjustable from 50 to 150 Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.

Controls:

  • Gain Control: rotary control; set the gain of the amplifier is match the input
  • Crossover Control: rotary control; adjust the crossover from 50 to 150 Hz

Auto Turn-On Feature: When 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 preamp level inputs are used, connecting the remote turn-on lead is required.

Q
i have a 2013 f150 super cab and i don't see any wires under my backseat. i have the regular stereo, not the sony edition. How would i power this amp and subwoofer? is it something i could tackle or be better off taking it to a car stereo shop?

If you are mechanically inclined, you should be able to do it yourself. Power should come from the battery of fuse box. Speaker inputs can be found on either door harness boot, if speakers are on the doors. If this seems tough for you to handle, then I suggest going to a shop. Expect an hour of labor
