Does it fit my car?

Find what fits your car

Can't find your exact car?

Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. But with custom ThunderForm enclosures, you can fill the nooks and crannies of your car, truck, or SUV with low tones that stand out.

MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. With "rotational molding," MTX ensures that each ThunderForm fits and blends inconspicuously into your vehicle. They're made of high-density polyethylene resin to curb resonances and deliver bass that's tight, hard-hitting, and way down low.

This molded MTX ThunderForm comes loaded with a premium-quality 10" Terminator subwoofer and installs under the rear bench seat on the driver's side of your 2001-2003 Ford F-150 Supercrew pickup (4-door). The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofer. Hardware is included. For the ultimate in Thundering bass, drive one with an MTX Thunder amp.

Important Note: This enclosure only fits vehicles that have a 60/40 split rear bench seat.

Product Highlights:

  • high-density polyethylene resin enclosure
  • single 10" Terminator subwoofer
  • 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.

MTX ThunderForms Reviews

2001 Ford F-150
Crutchfield Customer Review (What's this?)

This subwoofer is good and it is pretty loud in my truck. Its loud enough to feel throughout the car and in my seat, but its not going to vibrate anyone else's mirror or get on their nerves. I had to get a 200 watt kenwood amp to power the sub so I don't know how much that affected the performance.

Hands down a great investment for any F150 supercrew owner! Gives you full use of your rear seats without giving up your bass. Installs in about 10 min. and sounds great for 1 10" MTX4500 rated at 225 rms. I ordered mine unloaded cause I already have a few amps and I connectted it to Kenwoods 7202 rated briged at 460 rms at 4ohms. Broke it in and let me tell you this baby pounds! You'd think it blow, Not! Handels the power extremly well. Rap,R/B anything with bass!
