The sony subwoofer came with a sony stereo set (two speakers, receiver/tape/cd player, etc.). The sony receiver went out and I'm looking to hook this up to my sherwood receiver. However, the sony subwoofer has two wires coming out of it. One wire is the subwoofer jack and the other appears to have a "+" and "-" component with a special sony plug (that only plugs into their receiver). Can I cut off their special plug and hook it up to my sherwood receiver?
