tried searching but nothing. I am installing a 5 channel amp and a new head unit for someone. everything is hooked up and I have no sound through the door speakers. i tried to see if anything is going to the door speakers and nothing. I wired everything according to the harness and nothing is going to the speakers. I used speed wire to connect the amp speaker out puts to the back of the speaker harness at the radio. somehow the harness speaker leads do not go to the speakers in the doors. any help?
