I am SOOOOOOOOO much happier with how this turned out than the original fabric idea. I used black Rustoleum Hammered paint, its pretty close to matching the texture and color of the stock trim, just a little bit more glossy. I do have a few small bubbles and sand lines that show but really not noticeable unless you are really inspecting it. The thing is HEAVY, has to weigh at least 50 lbs with the amps on it.
Cant wait to spend another day gutting the rest of the car to wire and install my speakers...
