MTX Audio F150C04BK12-TN ThunderForm Loaded 12" Subwoofer Enclosure – 2004-2008 Ford F-150FITMENT NOTE: Fits 2004-2008 Ford F-150 SuperCrew (Crew Cab) and SuperCab (Extended Cab) 4-Door models. Does NOT fit 2004 "Heritage" (old 2003 body style), Standard Cab, or 2009-Up F-150 trucks.
The MTX F150C04BK12-TN is a custom-fit, vehicle-specific bass solution designed for 2004–2008 Ford F-150 owners who want deep, high-impact low-end without sacrificing interior utility. Unlike standard truck boxes that are limited to 10-inch drivers, this ThunderForm is engineered to house a massive 12-inch Terminator series subwoofer, providing the extra cone surface area needed for truly "Thunderous" bass extension. This "Loaded" version is non-amplified, allowing you to pair it with your choice of high-powered external amplification. Rotationally molded from high-density polyethylene (HDPE) and finished in a scratch-resistant Black, this enclosure fits perfectly under the driver’s side rear seat for a completely stealth, factory-integrated look.

Five Stars. Exactly what I needed for my space
Color: Black
I live in a small NYC apartment, so creating separation without making things feel cramped is always a challenge. This divider did the job perfectly.
It was easy to set up right out of the box. No complicated instructions, just unfold and place it where you need it. The size is great. It actually gives real coverage and privacy without looking bulky.
The fabric looks clean and professional, and the black color blends well with everything. I’ve used it to separate my workspace from my living area, and it instantly made my place feel more organized.
It’s also lightweight enough to move around, but still sturdy enough to stay in place.
If you need a simple, affordable way to create privacy or sections in a small space, this is a solid choice.

Good
Color: Grey
Works as it should, but one of the brackets on the leg broke while setting up. Super glue is holding it in just fine.

Not good for putting away daily
Color: Grey
This product may work of you are doing a full install, but is terrible for putting up and taking down daily. I have only had it 2 months and it is falling apart and will not stand straight.
