After reinstalling everything I get a consent static on the speakers. when I disconnect the speaker RCA to the amp, I hear the sub booming but the Z2 is not even playing anything. When I hook the RCA for the speaker, the speaker play the music but the static is always there. And when I turn the power off, THe speaker gets a loud brust static before it go off. HELP!! Any one know the cause, could it be the internal fuse for the RCA????

Check your ground wires. Make sure you have a good solid ground on all components.
