The MTX F150C04C12A-TN is a vehicle-specific, amplified bass system designed for 2004–2008 Ford F-150 owners who want high-output performance with a factory-matched look. This ThunderForm is finished in Charcoal to blend seamlessly with your truck's interior panels. While most truck boxes are limited to 10-inch drivers, this model is engineered to house a larger 12-inch Terminator series subwoofer, delivering a deeper and more powerful bass experience. As an "Amplified" unit, it includes a built-in 200-Watt RMS Class D amplifier specifically tuned to the enclosure’s internal volume. Rotationally molded from high-density polyethylene (HDPE), the F150C04C12A-TN is virtually indestructible and installs discreetly under the driver’s side rear seat, preserving your legroom and cargo space.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.
