About the MTX ThunderForms

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.

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 two premium-quality 10" Terminator subwoofers, and mounts under the rear bench seat of your select 2004-up Nissan Titan King or Crew Cab pickup. 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.

Features

Vehicle-Specific Custom Enclosure: This MTX ThunderForm enclosure is specifically designed to fit select Nissan Titan King Cab and Crew 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 under the rear seat. The jack stays in the factory location. 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
  • 6" Bit Extension
  • 10mm Socket
  • Socket Wrench
  • Wire Cutters
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.

Q
Does this box install faced up or does it face down ? I'm just asking because all the boxes I've looked at all say there designed to face down. Also was interested in anybody's opinion on how the Box sounds ? Thanks in advance Charlie

I forwarded your question to an Advisor and they responded with the following: It does install under the seat and the subwoofer do face down. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
