i just installed a 7 inch in dash dvd player and hooked up all the wiring correctly and everything, but when i turn it on only my door speakers go on. I know that i have to hook up the remote wire but my dvd player doesnt have a remote wire hook up. I was just wondering if it was even possible to hook up these speakers in the rear deck, if not i have a 12 inch alpine type r and amp that ill just hook up, i have a 2000 ls with the 8 speaker set up with the 6 disc in the glove box.
