Thanks for the input folks. Still trying to run down options as to what it would control since it's tied into steroe plug. 3Pillons thanks for the ideas. Factory subwoofer is still currently mounted under rear seat and opposite side is jack/tools etc for tire. No other space for extra subs since it's a SuperCrew and no signs of rear seat removal to mount extra sub boxes. I used to have a bumping stereo back in early 90's that would rattle your fillings and annoy most people(although I was very respectful and conscious of others) so I know some about stereos. Have asked brother his friends(stereo savy) on their opinions. Does not turn off rear speakers for sleeping kids or power to stereo with AUX key position or while in OFF key position. System is a factory Ford Audiophile radio/6 disc changer. Can change sound system setup for seat config. Driver, rear, passenger, ALL. etc Still researching........
