Waddup guys. I ran into a problem while installing a system in my buddy's car. I ran the power wire through, remote wire through, and grounded the wire onto the chassis, hooked up the amp but the amp won't turn on. I tried 3 different amplifiers, checked all fuses, checked the main power wire fuse. I also tried connecting a wire from the 12v to the remote but it still won't turn on. The amp worked on another buddy's car. Any ideas?
