i made a small box out of half in OSB board that the CD player just slid into, and screwed it to the plywood shelf in the back of my GT. i ran the wires down through the hole where the tire hold down hooks to with a protector on them. from there i went under the carpets into the fuseblock. i made another small panel from OSB and put 2 6X9's and 2 4's in that, covered it with carpet and left the origional thin plywood piece covered with vynel intact and uncut. you can use a remote to operate the CD player, or if you're like me you can reach back under the flap without looking and memorize all the buttons.
