Custom-fit enclosure for 1997-03 Ford F-150 and 1997-00 F-250 Light Duty Regular Cab (Charcoal)
Our take on the MTX ThunderFormsby Crutchfield's John Pollard
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.
This molded MTX ThunderForm comes loaded with two premium-quality 10" Terminator speakers. It mounts behind the seat of select 1997-2003 (and 2004 "old body style") Ford F-150 and 1997-00 F-250 Light Duty regular cab pickups. It replaces the tool tray, if present. Hardware is included.

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select 1997-2003 Ford full size, standard cab pickups. 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 behind the seat. It replaces the tool tray, if present. 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.
Woofers: The ThunderForm enclosure is loaded with two 8Ω, 10" MTX Terminator subwoofers. The subwoofers are wired in parallel to a single terminal, presenting a 4Ω load to your amplifier.
Tools Required: The manual provides this list of required tools:
- Powered Screwdriver
- #2 Phillips Head Bit
- 8mm Socket
- 1/4" Socket
- 7/32" Socket
- Wire Cutters
- Terminal Crimper
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.

Thanks for your question. Unfortunately Crutchfield gets the pics from the manufacturer as these are not located in our warehouse. Even on the MTX website there are no additional pictures. You may be able to reach out to MTX at 800-556-2888 for further assistance. I'm sorry I couldn't be of more help.[ Kenny May 16, 2017 ] Staff
It's a dual chamber enclosure with 1.8 cubic feet of airspace (0.9 per sub). I hope that helps. My Bio: https://www.crutchfield.com/Support/Bio.aspx?bio=5 [ Ryan May 20, 2017 ] Staff
