hello everyone I was wondering if You had any suggestions about getting rid of the noise from my audio system. I believe the noise comes from the alternator and it makes a high pitched whining noise that is VERY annoying. I put resistor plugs and plug wires on it but that did not help at all. Someone suggested that i put another battery in the back and wire the radio to that instead, bypassing everything. Any suggestions will be a big help! Thank you!
