I have a problem with my amplifier circuit (LA4597).
I tested it (12V). It turns on and the speakers and fine and silent.
But when I try to add an audio source (RCA) within the circuit, the speakers begin buzzing. And when music is played, the output comes out very loud and distorted and is being mixed with the buzz.
I followed the diagram on the datasheet to the letter. I wanted this to play music from a phone or a PC. What am I missing?
