annoying whine when trucks engine is on and off!

[89sasha10]

when my key is turned to on ACC or whatever it is (engine not running but key is on) there is an annoying buzz in all my speakers and my driver side speaker gets little to no actual music, and when car is on theres a high pitched whine along with that buzz that matches the trucks rpm, and i can even hear when i turn my turn signal on in my speakers, and my driver spearker cuts in and out. im freaking losing my mind here. please help.

Just start? You change the stereo? Shorted speaker wire or bad ground possibly.

Have you been in the dash or is this a factory radio?

ill check the amp ground, i know its screwed into the floor board somewhere, not a factory radio, nothing in this truck is factory. i have no clue where my battery ground is, unless thats the same as the amp ground
