---Diagnostic light ON--Crunch Amp--How to fix?---
trying to install this small amp in my car but the Diagnostic light is On. (red) suppose to be green. in the manual it says
"If the Diagnostic LED goes on at this point, then you know there is either a short in the RCA cable or the headunit is sending DC voltage into the amplifier."
my headunit is new. how can i fix this?
