So im trying to figure out where to run wires but find it almost impossible to not cross wires at all. I know the power wire and RCA should not be close. I think I can avoid that, but when running the right and left front speaker wire to components at some point the left speaker wire will cross the power wire (power wire will come through the firewall on the driver side). Is this ok? I think I could possibly avoid it but I would have to make the speaker wire fairly long. What do you experts do when the power wire and speakers wires get too close?
