LOUD high pitched squeal\buzz\ringing
2007 GT with #15833071 Monsoon amplifier.
My Father's G6 is making an incredibly loud high pitched sound seemingly from all drivers side speakers.
I've tried powering the radio (stock HU) off.
Pulling the radio fuse.
Took a wire brush to the two ground wires near the interior fuse box.
Cut ignition and pulled key out...yes it persists even when no one's in the car!
Finally I unplugged the amplifier...it stopped
I'm ripping my hair out. Hoping SOMEONE, anyone...has heard of this problem before.
