Hi, when im using the car in accessory mode there are no high pitched noises but as soon as i turn the key to ON or START the car i can hear this high pitch noise from back speakers, i had disconnected the cables from the amplifer and it disappeared but came back once i plugged it back in. I have no clue on how i am able to fix this, anyone have ideas?
