MTX Audio FMUST05BK12-TN ThunderForm Loaded 12" Subwoofer Enclosure – 2005-2014 Ford Mustang (Coupe)

FITMENT NOTE: Fits 2005-2014 Ford Mustang Coupe (S197 Platform). Does NOT fit Convertible models, the Shaker 1000 factory system, or 2015-Up (S550) models.

The MTX FMUST05BK12-TN is a custom-engineered, vehicle-specific subwoofer solution designed to add deep, hard-hitting bass to your 2005–2014 Ford Mustang without taking over your trunk. This "Loaded" version features a high-output 12-inch Terminator series subwoofer pre-installed in a rotationally molded high-density polyethylene (HDPE) enclosure. By utilizing the passenger-side rear corner of the trunk, the FMUST05BK12-TN provides a massive audio upgrade while leaving the main cargo area open for your gear. Because it is non-amplified, this enclosure is the perfect choice for Mustang owners who want to use a dedicated external amplifier to drive their system for maximum performance and customization.

Key Features
  • Vehicle Specific Fit: Precision-molded to fit the passenger-side trunk corner of 2005-2014 Ford Mustang Coupe models

  • Space-Saving Corner Mount: Engineered to tuck into the unused corner of the trunk, preserving maximum cargo space for daily utility

  • Sealed Enclosure Precision: Features a 1.2 cubic foot sealed internal volume, providing the ideal acoustic environment for tight, punchy, and accurate bass response
  • Customizable Power: Features high-quality terminal posts for a secure and direct connection to any mono or bridged 2-channel amplifier
  • Premium Driver Build: Subwoofer features a lightweight polypropylene cone, durable rubber surround, and a 1.5-inch aluminum voice coil for reliable high-volume performance

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Great ball!
Color: Ultra, Size: Large
Our puppy loves this ball. It has held up well so far, it’s about 2 weeks now of large breed pup play. It’s been outside for the last week, rain or shine, still in working order. Not as big as I thought it would be though. No squeak, bounces well. Thick rubber like material, that can be depressed when biting down.

Durable, even for a Great Dane!
Color: Ultra, Size: XXL
I've bought many tennis ball sized ChuckIt balls in the past (for medium sized dogs we've owned), so when we knew we were going to be babysitting our daughter's Great Dane, I bought a bigger one for her. The 4" is perfect for her! She plays catch with it, but also likes to gnaw on it. It holds up great!

Another great product from Chuckit!
Color: Ultra, Size: XL
Exactly the high quality that I've come to expect from Chuckit! The plastic/rubber used in their products is extremely tough yet gives enough that it's hard to actually pierce the it and tear apart. We have had Chuckit! Sticks and Balls with launcher for years and love them all. This particular ball is pretty big so my 45 pound pit mix struggles to pick it up but that's part of the fun for him. My 85 pound pit mix can pick it up no problem. The only "complaint" is that the two of them have been having so much fun with their new ball, they have already knocked something over and broke it. 😁
