[QUOTE="LordX, post: 8177200, member: 613621"] Update: I turned off the head unit - and pressed the button for it to flip back inside (its a flip out model) - and then I turned off the car - and turned it back on to see if the whine was still there - my thinking being that if the head unit is off - the amps are off - and the whine should be less or gone. It wasn't. The whine was still there at the same volume as before. So am I safe to say that the head unit is not the cause? I am wondering now if the whine is coming from the alt and I can hear it in the car. The stock alt is now powering two batteries - and I wasn't able to use my isolator - so I have two different types of battery (AGM Car Audio battery and reg flooded stock battery) wired in parallel. I don't know if this poses an extra strain on the alt - perhaps I should create a new thread? [/QUOTE]
