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 mounts under the rear seat of your 2009-up Ford F-150 SuperCab, with no loss of leg room. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. For the ultimate in thundering bass, drive one with an MTX Thunder amplifier.

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.

Terminator Woofer:

  • Asymmetrical Linear Drive System (ALDS): The Asymmetrical Linear Drive System consists of a flat, progressive spider that improves suspension and an extended vented pole piece that smoothes out the cone's linear motion. The result is high output and low distortion.
  • Spider Plateau Venting: Heat from the voice coil is vented through metal-mesh covered vents that surround the back of the spider.
  • Voice Coil: The voice coil is wound on a high-temperature former to promote high power handling.
  • Strontium Ferrite Magnet: The strontium ferrite magnet yields a highly efficient speaker.

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.

MTX Amplified Thunderform 2012 F-150 SuperCab

Written By JTN, S. Side Chicago on Friday, March 16, 2012

All connections on the nylon Molex connector on the supplied power harness should be double checked. The ground wire pulled out of the connector with minimal force. I removed each pin receptacle from the connector and soldered the wires. The supplied fuse block that connects power MUST be checked for continuity with the fuse removed, ie should show no continuity. As I was hooking up the fuse block to the battery the end opposite of the ring connector shorted out on the negative battery post with no fuse present. I cut open the soft potting material and discovered that the stranded conductors on each side of the blade terminal receivers were contacting each other. I feel fortunate that I caught this for obvious reasons. When I removed the unit from the shipping material I noticed something rattling inside. I removed the speaker and found several small pieces of fiberglass.

The vehicle specific instructions supplied by Crutchfield are awesome! The the high level inputs via the RCA pig tails make for easy installation, also when using the speaker level input via the RCA jacks the auto on feature works great. The fit is perfect, the black carpet exterior matches nicely with the black carpet interior. I am very pleased with the sound quality and the built in crossover, gain and remote bass control make fine tuning enjoyable.

Pros: Good sound. Perfect custom fit. High level input / remote on via supplied RCA harness.

Cons: The entire supplied hardware/power harness package must be mechanically and electrically tested before installation.

You will want to contact an Advisor by phone or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff  Dec 28, 2013 ]  Staff
