Default Another alternator whine thread

I have.a.horrible alternator whine now that I threw my 360.2 processor in the loop. Weird thing is I can hook RCAs straight to.amp from headunit and its perfectly fine. Amp and processor and pretty close to one another. I plan on grounding the headunit RCAs just for assurance. And running the headunit ground to the location of the rest of the grounds. Any other.help?

Common ground is a good start.

I would slap a ground loop isolator on it, if it's still there try it in a different car, if it's still there it's in the processor

Ground loop only is a bandaid. That will be last resort.also read they hurt your preout voltage on RCAs. So we'll see
