Nissan 370Z Forum - View Single Post - Noise only when Engine is running (Buzzing sound

Switched out to RCA ($9). The buzzing from the HU and the Amp is completely gone. I can finally use the gain boost from the amp. Cut the 2 grounds cable of the HU to the harness. The thick black wire doesn't go anywhere. I grounded them both to the frame.

There is a very small buzz (even when either RCA's end are unplugged), it's very faint, can't hear when the music is even at volume 1, you can only hear if you kind of try to listen for it. I have no idea where this comes from. Only when engine is on.

Thank you everyone for your help!!!
