[QUOTE="HardofWhoring, post: 8830872, member: 674149"] Wait, so the whine only happens when the amp is connected, and only from the speakers that are connected to the amp? - If this is true, it has to be your amp's ground. Even if it's a small amp, the grounding path is still the same, (the path of least resistance, and ending at chassis). If it's anything else, can you connect speakers directly to the head unit, and speakers to the amp, and see if they all whine? If it's only the amp speakers then it's your amp's ground. If it's the head unit speakers too, then it's one of your other grounds. Your amp should be grounded to bare metal, have to clean it to bare metal if it's paint or coating, [/QUOTE]
