There's a Thunderstorm in the forecast, and it's headed for the wasted space in your vehicle. ThunderForms preserve all the legroom in pickup trucks and all the cargo space in SUVs. Each ThunderForm is an acoustically-designed, non-resonant, airtight enclosure, with the correct internal volume to yield optimum bass response from its subwoofer.

So what makes ThunderForms different than a standard sub box? MTX engineers design each ThunderForm enclosure for optimum performance in your specific vehicle's acoustic space. Using state-of-the-art rotational molding techniques, and exotic high-density polyethylene, MTX creates a sculpted masterpiece of a sub box, beautifully finished to blend with your interior. And they sound as good as they look, delivering bass that's tight, accurate, hard-hitting, and way down low.

This molded MTX ThunderForm comes loaded with a premium-quality 10" Terminator speaker and replaces the factory console in in the following vehicles: 1999-00 Cadillac Escalade, 1992-94 full-size Chevrolet Blazer, 1992-99 Chevrolet Suburban, 1992-2000 GMC Yukon, and 1995-00 Chevrolet Tahoe. It has built-in cup holders and a storage area that's perfect for palm-sized computers and other office tools. For the ultimate in Thundering bass, drive one with an MTX Thunder amp.

Product Highlights:

  • high-density polyethylene resin enclosure
  • single 10" Terminator subwoofer
  • replaces the factory console
  • frequency response 35-150 Hz
  • power range 50-225W RMS
  • 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

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to replace the factory console in select 1992-2000 Cadillac, Chevrolet, and GMC Escalade, Suburban, Yukon, Tahoe, and full-size Blazer 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. The color of the enclosure matches factory GM colors. Three cup holders (2 for the front and 1 for the rear) and a tray are molded into the top of the enclosure. It is a down-firing acoustic suspension (sealed) chamber.

Woofer: The ThunderForm enclosure is loaded with a 4-ohm, 10" MTX Terminator woofer.

Mounting Location: This enclosure is designed and molded to mount between the front bucket seats, replacing the factory console, with the woofer firing downward. Note: The provided dimensions are taken at the widest points of the enclosure. Keep in mind that these enclosures are custom made to fit in this particular vehicle, so the enclosure will fit properly in only one specific location. Mounting hardware is included to bolt the enclosure to the floor of the truck.

Tools Required: The manual provides this list of required tools:

  • Phillips Head Screwdriver
  • T50 Torx
  • 15mm Socket
  • 10mm Socket
  • Power Drill
  • Ratchet
  • 6" Ratchet Extension
  • 5/16" Wrench
  • Wire Crimper
  • Wire Cutters
  • 3/8" Drill Bit
Note: The manual provided is for both the amplified and non-amplified versions of this ThunderForm. Some of the tools may not be needed for this non-amplified ThunderForm.

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 install in 93 Full Size Blazer

Written By Matt, Dallas/Austin, TX on Saturday, January 07, 2012

Its well constructed, easy to install, and provides more bass than you might expect.

I am especially happy to find out that the sub is very musical, and produces a nice tight sound, and isn't boomy. Also the placement helps to reinforce the soundstage, and prevents it from sounding like you have your back to the stage. Sub's can be "localized" its just not as apparent at the lower frequencies. That all said, it was money well spent.

Pros: Its a simple, well made solution, for those that don't want to give up the Utility of there Sport Utility Vehicle. Surprisingly deep bass, that is very tight and musical.

Cons: The 225W RMS/ 700W Peak rating, had me searching in circles for an Amp that would not be over kill on RMS, but still break 300w Peak. Finally I figured I wold risk it and got a Sony XM-1S 290W RMS @ 4ohm, peak 500w, and called it a day.

Get everything you’ll need to enjoy your new MTX Thunderform

You'll need speaker wire to get the signal from your amp to your sub.
If you don't already have these in your toolbox, you may find them handy.
