Clarification Request

Posted by yourcoins on Jun 03, 2009

I have seen power supply problems on these amps, does it do it when the rca's are connected AND disconnected?

Posted by pbabin on May 30, 2009

Is the power/protect LED red or green?

try grounding the rca shield to see if it stops, if it does you have an rca ground problem in either your head unit or your amp
