hello. i bought this deville with a pioneer cd player installd and it workd great. the unit crapped out. i need a wiring diagram so i can re wire it, the right way as they had the acc ran all the way to the fuse block and stuffed it in a fuse socket. now is there a way to wire it so that the radio will stay on till you open the door? also is there supposed to be speakers in the front doors? all i have is the two rear speakers, and the two little tweaters in the door. there is a space for what looks like a 6x9 in the dash that is not there. is this correct?
