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 behind the rear seat of your 2000-06 Ford F-250 or F-350 Crew Cab — your truck must have the rear bench seat. Your jack stays in its factory location, but you'll have to move your tools to the passenger side of the enclosure. 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.

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

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

MTX Audio Subwoofer: The ThunderForm houses a single proprietary 0.35 ohm woofer. The woofer features a long excursion voice coil and is designed to take full advantage of the efficiency of the enclosure's Class D amplifier giving you powerful, low frequency bass extension

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.

Protection Circuits: The amplifier features over voltage, over current and voice coil short protection to protect the amplifier and woofer.

Built-In Crossover: The crossover frequency can be varied from 50Hz to 150Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.

Remote Bass Control: The ThunderForm comes supplied with a wired remote bass control that allows you to remotely adjust the bass from the driver's seat. This is a wired control which needs the cable to be run from the drivers seat to the location of the ThunderForm so it can be plugged in to the ThunderForm.

Smart-Engage Feature: When the speaker level inputs are used, the system will automatically turn on and off with the radio. This time-saving feature eliminates the need to remove the head unit when installing the ThunderForm.

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

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.
