MTX Amplified ThunderForms

Overview

Our take on the MTX Amplified ThunderForms

Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. But with custom ThunderForm enclosures, you can fill the nooks and crannies of your car, truck, or SUV with low tones that stand out.

Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. But with custom ThunderForm enclosures, you can fill the nooks and crannies of your car, truck, or SUV with low tones that stand out.

MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. With "rotational molding," MTX ensures that each ThunderForm fits and blends inconspicuously into your vehicle. They're made of high-density polyethylene resin to curb resonances and deliver bass that's tight, hard-hitting, and way down low. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers.

This molded MTX ThunderForm comes loaded with one premium-quality 10" Terminator subwoofer, powered by a specially-designed 200-watt mono amp. It mounts behind the rear panel (replacing the cargo net) on the passenger side of the 1991-2001 Ford Explorer, 1991-94 Mazda Navajo, and 1997-2001 Mercury Mountaineer. Hardware is included.

Features

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select 1991-2001 Ford Explorer, Mercury Mountaineer, and Mazda Navajo 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 in the cargo area on the passenger's side; it replaces the storage pocket or factory subwoofer (whichever is present). 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.

  • Phillips Head Screwdriver
  • T50 Torx Driver
  • 15mm Wrench
  • 8mm Socket
  • 1/4" Socket
