My dad has a monstrous stereo system in the living room and I figured it's time I use it to enjoy my gamecube/PS2 to the fullest (if possible). The system consists of an amp, a digital signal processor, casette deck, cd player, AM/FM stereo Tuner Preamplifier, and two massive standup kenwood speakers. What would I need to do to use this equipment to provide sound for my consoles?
