Now I know the problem. When looking at the Arc amp in daylight, it's difficult to tell when the amp has power. But it's evident at night because a power light shines up under the dash. The so-called professional installer I used has connected the amp turn on wire to a keyed circuit instead of using the turn on wire from the head unit. Therefore the "pop" when the head unit shuts off.
I'm headed to that shop 1st thing tomorrow!
Thanks to everyone for your input.
