High-Level or RCA, alternator whine
Hello everyone,
I have a question. I have some alternator whine and I traced it back to being the RCA outputs of my aftermarket headunit. Now I don’t know what I should do. Buy a new headunit that would set me back quite some money, or connect the High level outputs of the headunit.
Also for my headunit RCA I only have left and right but would like to have front and rear to. The normal wires for the headunit do have those.
That would mean I can connect the output wires from my headunit to my JBL A704 high-level inputs.
Would this make the music quality worse? I tried grounding the headunit more but it didn’t work. When connecting a device straight into my amplifier there is no whine.
