MTX Audio FMUST05BK12A-TN ThunderForm Amplified 12" Subwoofer Enclosure – 2005-2014 Ford MustangFITMENT NOTE: Fits 2005-2014 Ford Mustang Coupe and Convertible (S197 Platform). Does NOT fit 2015-Up (S550) models.
The MTX FMUST05BK12A-TN ThunderForm is a custom-engineered, all-in-one bass solution designed to bring deep, hard-hitting low-end to the 2005–2014 Ford Mustang without sacrificing your trunk's utility. This vehicle-specific enclosure is rotationally molded from high-density polyethylene (HDPE), creating a virtually indestructible and resonance-free housing that fits perfectly into the passenger-side rear corner of the trunk. While most factory "premium" audio systems use smaller drivers, this ThunderForm is loaded with a high-output 12-inch Terminator series subwoofer for massive air movement. This "Amplified" model features a built-in 200-Watt RMS Class D amplifier specifically tuned to the enclosure's volume, providing a seamless, factory-integrated look with the "Thunder" that MTX is legendary for.
Key Features
- Vehicle Specific Fit: Precision-molded to fit the passenger-side trunk corner of 2005-2014 Ford Mustang Coupe and Convertible models
- High-Output 12" Subwoofer: Pre-loaded with a 12-inch Terminator series driver, providing significantly more bass extension and impact than smaller factory subwoofers
- Integrated Amplification: Built-in high-efficiency Class D monoblock amplifier delivering 200 Watts RMS (400 Watts Peak) of clean, dedicated power
- Corner-Mount Stealth: Engineered to utilize the unused corner of the trunk, leaving the main cargo area open for gear and groceries
- Indestructible HDPE Construction: Rotationally molded high-density polyethylene is resonance-free and finished in Black to match your trunk's trim
- Smart Engage Technology: Automatically powers the system on when it detects a signal from the factory speaker wires (no remote turn-on wire required)
- Universal Connectivity: Includes both RCA (low-level) and speaker-level (high-level) inputs for easy integration with Shaker systems or aftermarket radios
- On-The-Fly Control: Includes an External Bass Control (EBC) remote knob, allowing you to adjust the subwoofer volume from the driver’s seat
- Acoustic Performance: Sealed 1.0 cubic foot enclosure provides tight, accurate, and musical bass response
- Frequency Response: 24Hz – 160Hz
- Dimensions: 15.5" H x 23.5" W x 10.5" D

It suits me very well
I have a very large room. Its layout is perfect for me to convert into two rooms. Adding this screen is perfect and matches the style of my house.

Nice quality, looks brand new even with daily use! Worth it!
Size: 6 Panel, Color: White
I got the Rose Home 6 panel room divider folding privacy screen and I LOVE it. I use it every day - extending it out to both block the sun, provide a backdrop for my plant wall, use as a backdrop for zoom calls, create privacy at night in front of the big windows and clear doors, and make impromptu study privacy walls in the office. This 6-panel has been the GOAT! Even though the screen is made of a woven paper material, it is still going strong despite daily use and has NOT broken anywhere. The frame is taller than other folding screens I've purchased and this one is also heavier and sturdy. Additionally the hinges fold open in BOTH directions (some screens only fold open in 1 direction like a Z). I use the folding screens indoors, but they have no issue with the AC or fans for wind resistance indoors. Sometimes I use them to hide storage or junk in the corner and make the room look neater. I also have a different brand that is the same material but has 8 panels and I love them both. I got 2 others that were made from synthetic canvas webbing belt/leash fabric and those break so fast - I just had to throw 1 away. This one is worth the money, even after daily use, it looks brand new!

Already assembled!
Size: 8 Panel, Color: Natural
Came way sooner than the estimated delivery date and it looks awesome! Biggest plus is it came ALREADY ASSEMBLED! I was expecting self assembly but maybe that's on me for not reading the specifics. Hoping it's the right size for my new studio apartment. So far the look and functionality is 10/10
