programming the deck, Program my deck for my sub Options

[acenova]

Alright, you know how when you get a cd player w/o the sub then it doesn't recognize the fact that there's the sub there but when you get a sub you're supposed to program the deck for the sub? I think you do it for most all modern decks. I just installed my sub and it sounds damn good, but I'm not getting enough power to it to realize it's maximum potential and I think it's because I haven't programmed my deck.
-Anyone know if there's a general way to program the deck and get to the "secret" menu that has the sub feature to turn on and off?
I'd check my manual for it, but I have misplaced it for the time being.
