Can't Fix my alternator whine.

[bloodhound50 10+ year member]

So I have really annoying alternator whine, its worse when its cold and wet out and only occurs when the car is running if anyone was going to ask. Me and my friend tried grounding the RCA's on the HU and on the amp. we checked the grounds. I might buy a ground loop isolator at wal*mart. Any Suggestions.

Re run RCAs, new RCAs, new ground on HU and amp, could be a lot of things.

Try running your power wire on one side of the car and the RCA's on the other. I don't know if this is true or not, but hey, can't hurt.

You are always supposed to run the power and signal leads on opposite sides of the car, of course that will help.

Run your power and remote line on the same side of the car as your battery, and your RCAs on the opposite side. Reground your amp, make sure you have a clean piece of sheet metal (sand it down) that is a part of the body. Do not use a secondary panel for your ground like your trunk or a door or even a screw sticking out of the the chassis.

i always run my signal and remote wire on the same side, and never have any problems with it.

He said he already grounded the RCA's on the HU

Guaranteed he didn't do it like he should've.

That is your problem. There is really no other explanation for it.
