Ok so I got my alpine 9815 in the mail today and i got my wiring harness and the wire twist connects. I followed the instructions according to the alpine manual and the directions for the wiring harness.....I have a display and everything....but NO SOUND!!! I'm sure I connected the right wires for the speakers, but there isn't any sound at all coming from them. It's not the speakers because my old radio was working today and has been. HELP ME PLEASE!
