First of all please forgive my stupid question, i have searched google and the forums with no luck. I have a marantz pm7200 amplifier hooked up to a marantz dv6500 dvd player, connected to 2 dynaudio audience 52se's. Anyways, a friend just gave me his canton as 22 subwoofer and i cannot for the life of me figure out how to hook the thing up to my amplifier. Do i need some type of extra equipment to hook up a sub to my system? Thanks in advance for any help!
