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 molded MTX ThunderForm comes loaded with a premium-quality 12" Terminator subwoofer modified especially for amplified Thunderforms, with a specially-designed amp that puts out 200 watts of power. It installs in your 2001-2004 Ford Escape in the driver's side rear panel. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers. Hardware is included.

Product Highlights:

  • custom-fit powered subwoofer
  • enclosure mounts to the driver's side rear panel
  • special-design 12" Terminator subwoofer
  • built-in 200-watt RMS Class-D amplifier
  • high-density polyethylene enclosure
  • variable low-pass filter (50-150 Hz at 12 dB per octave)
  • preamp- and speaker-level inputs
  • 20' power harness included
  • warranty: 5 years (free repair or replacement for 2 years, prorated replacement for years 3 through 5)
  • Our 60-day money-back guarantee

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Features

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 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.

High/Low-Level Input: The unit offers one pair of RCA inputs that can be used with a High Level (speaker-level) or Low Level (preamp-level) input signal. A pair of High Level input wires (tinned bare wire-to-RCA plug) is included.

Auto Turn-On Feature: When the Thunderform is connected using a speaker-level input signal, the amplifier will automatically detect the signal and turn on and off with the radio. The auto turn-on feature does not operate when a preamp level input signal is used, therefore the remote turn-on lead should be connected.

External Bass Control: The external bass control allows you to adjust the bass level from anywhere in the vehicle.

Terminator Woofer: This enclosure comes loaded with one 12" Terminator woofer.

Note: The woofer has an unusual impedance, specifically designed with the amp, and cannot be replaced with a standard MTX model.

Molded Enclosure: The molded, high-density polyethylene resin enclosure resists flexing and dampens resonance.

Controls and Inputs

Controls:

  • Gain Control: rotary control that allows you to set the gain of the amplifier
  • Crossover Control: rotary control that allows you to adjust the crossover from 50 to 150 Hz

Inputs:

  • Input: left and right RCA jacks; these jacks allow speaker-level input when the supplied RCA high-level input wires are connected
  • EBC: mini-jack for use with supplied external bass control
  • Harness: 3-pin jack for use with supplied wiring harness
  • Fuse: installed 20A ATC fuse

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.
