The aftermarket door sub amp is wired for 2 ohms and matched to CDTs wired for 2 ohms. I called the amp manufacturer today (Arc Audio) and they offered no solution for the popping noise at shut down. I'm thinking the Arc amp is still receiving power after the head unit shuts down, and the shut down of the head unit is causing the pop. If that's the case, I don't know how to prevent this problem. I'm going back to the installer this Friday. I will ask them to be sure the Arc is properly grounded and that they are certain that the head unit turn on wire was properly interfaced with the Arc power on connector.

Would you have any other ideas?
