I recently hooked up my comp set, and there was a horrible screaching noise from the speakers at low volume. I checked bad ground, bad rca's and it was none of that. Then I wrapped a piece of wire around the rcas behind the headunit and it stopped the problem. Why? You shouldnt have to do that I am assumming.... It seems like the problem is obvious...but I can't just figure it out. If you move the ground on the amp, you can hear the movement u are making with the wire..if you move it back and forth. Just wondering why wrapping a piece of wire around it fixes it. And I am not even sure if it is good or not, because I just blew my comps..not sure if it was from that or from just to much power.
