If the sub is moving / producing sound, the Amp is getting power, and is turning on from the remote wire. Did you adjust any of the gains (level adjustments) on the amp?
You say you got a new head unit, did you go through the radio menu / settings, and make any adjustments for the RCA outputs for the Amp signal? Your problem / need for adjustment probably is in the radio itself. What is the make / model of the radio (Pioneer BHS4200 or whatever).
