nothin should happen the amp might shut off thats about it. ive touched them a bunch of times. check your fuse's and then check the wires.

 

yea, nuthin should happen to the amp, i check the fuse and wire, it all fine, i even try different wire, it still make that high pitch noise, u think somethin wrong inside the head unit?
