Im installing new door speakers, and the wiring for the stock harness doesn't seem to work. Also, I can't seem to find the wires for the doors at the harness anyways. Plus, I am going to be amping the speakers, so I will have to run my own wiring it appears. How do I route it through the door into the car? Looks like Im going to have to take the door panels off, how do you do this?
