I installed new speakers and sub back in October. Everything has worked perfect until yesterday. Now I have no audio, I had another stereo to hook up and see if it was that. Long story short my sub was beating with the song I was playing but still no audio. I have no idea what is happening
Check the Radio Fuse,
Check your RCA connections and/or Speaker wiring connections
Check Fuses for Amplifier
Check Ground wiring for Radio and Amplifier as well as Power and remote wiring
I would start with these and see if the issue persist or not. there are a few other things to be checked as well. Id start with these first
