Stereo WTF short?

So lately I've noticed my stereo (all stock) was making a weird buzzing noise. Not too weird with how old the stereo is but as of the last two days I've noticed it making some weird *** noises. The turn signal clicker (yes, the turn signal clicker sound) is now coming through the stereo, and there is a high pitch squealing noise coming through the speaker that directly relates to how high the rpms are at. I can hear it change when it shifts in/out of gear. I'm really REALLY confused and am half laughing at it because it's entertaining.

What could possibly cause this? Where could it short that would cause this to happen? And yes, it does go away when the stereo is turned off.

Sounds like something a ground loop isolator might fix, but I don't know why that's happening or how you'd fix it. Maybe an aftermarket radio would take care of the problem. Sorry I can't be of more help, I'm dumbfounded.

Possibly a bad alternator if not the head unit. Can you hear the turn signal with the motor off?

Alternator whine is typically associated with ground loops. Being as your stereo is completely stock, I'd say it's probably not that. More than likely it's a bad ground. Try making a new one.
