Default high pitched buzz coming from inside

The sound sounds like its coming from behind the stereo. its an electrical whine. i had heard it once before, replaced my bad water pump, now im hearing it again. im assuming people have experienced this, i ahve heard it in other cars, but if yall would like a video i can post 2. the electrical whine corresponds wit hthe throttle

its annoying

heresa vid. had to step down quality to email it

How much aftermarket stuff do you have hooked up to your car. In my old car, i have a amp and some huge subs, so when i had everything turned up to the max drawing the most power from the battery, you could hear it whine when giving it gas, almost like hearing the car charge the battery at the same time.

Mine sounds the same after it came back from repair work, had the motor out the bottom. What grounds would they remove to take the motor out. Sorry don't want to hijack your thread but it fits me too.

There's three main ones, one in the back of the drivers cylinder head, one behind the alternator to the frame rail, and one near the starte/motor mount to the battery.

May also want to check the ground on the stereo head unit and ensure it's properly attached or run an independent. But also check for power steering whine but to me it sounds like its coming through te stereo. If you turn up your radio does it get louder or change? Or if the stereo is turned off?
