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. 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. 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.

Built-in 200-watt amp and 10" sub
This amplified ThunderForm comes equipped with a cool-running 200-watt amp that's custom designed to provide optimal power to its 10" FPR subwoofer without straining your vehicle's electrical system. MTX's Electronic Bass Control (EBC) lets you adjust the bass level from the driver's seat. A variety of inputs allow easy integration into your vehicle's sound system, and the included 20' power harness simplifies supplying power to the amp.

Made for your vehicle
This enclosure installs under the rear passenger side seat of your 2001-05 and 2007-10 Ford Explorer Sport Trac. Please check with us before purchasing by using the vehicle selector on our site, or calling an Advisor at 1-888-955-6000 to verify fit information.

very poor product

2004 Ford Explorer Sport Trac

very poor product

Pros:

Cons: I had a previous post where I tried the DIY install for this and ended up taking it to the shop because it had very little audibility after install. The shop replaced the provided RCA cables to correct the problem. I was so hopeful that after spending the weekend on this thing that it would sound good. This system, after professional install, sounds like a trash 6x9. Crutchfield is handeling this very nicely. They are sending me a return barcode label. Save your time and the headache.

2004 Ford Explorer Sport Trac

this product is sold as a DIY. thought this was a weekend project that would save me a couple bucks. Started yesterday, pierced the firewall and ran the wires through the proper channels. Instructions weren't that good but you can improvise. Anyhow, I got it all hooked up and it sounds like a 15 watt boombox. got it at the shop now so they can do it for me. I'm hoping it will sound good when I get it back but - Not A DYI Project and prepare to not save money on this one.

Features

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select 2001-2011 Ford Explorer Sport Trac 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.

Subwoofer: This enclosure comes loaded with one 10" FPR shallow mount 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.
