Control wire? You mean the REMOTE wire for your amp right? The sub input would go through the amp first so depending on how you set it up, you might have to turn on the power to the amp and shut it off when your done but who knows, maybe there is a way. I am pretty sure my buddy doesn't use his REMOTE wire, just uses a positive/negative lead from the amp and turns on his power supply when he turns on the TV, DVD, ETC.....
