First of all to answer a couple of previous questions, i did not have DSP. Next is, I do not have a cd changer, or anything for that matter in that compartment such as a dvd/nav changer, etc. the only thing that i had there was the useless bmw stock amp which sucked btw, and was rid of...the amps were mounted on i believe a 3/4" or 1/2" plywood that was bracketed in from the top and bottom...it was also carpeted black because the bare wood was showing...i will take pictures with my digital camera which should show it in great detail...and when i uprgrade my head unit with a double din kenwood excelon in a month or so, i will probably fit in the dvd changer somewhere in the glove box, or maybe use the new slim ps2, and mount that inside the back center arm rest, with a cutout for the flip open disc tray...any ideas welcome....thanks
