Radio whine when driving with A/C on

[tbrewster]

The title says it all. I have a stock radio so this is kinda surprising. When the A/C is off the whine goes away.

Bad ground somewhere perhaps? Thoughts?

Sounds like a bad ground. Start with the engine ground and starter grounds..

Same here man I could never figure the shit out, I've tried for the past 2 years and just gave up.

You sure its the radio not the alternator whining? If its the radio it sounds like its electrical noise.

Did you figure this out? I saw a similar instance on e30Tech where they thought it might be the A/C Expansion valve.

I have a similar issue.

If it's the radio whining for sure might want to check the rf interference ground attached from the core support to hood. small silver one left side.
