just got my 96 del sol Friday, removed the oem radio, installed all the wires for my subwoofer and amp, installed my kenwood cd player everything was working great this morning when i left for work at 6am and when i got off i started my car and the only things working were the subwoofer and the cd player but none of the front 2 or rear 2 speakers had any sound coming from them, i checked all the connections in the rear of the cd player everything was secure and all my fuses were not broken. What's causing this issue? thanks
