Alright so I know there are some big surround sound people here. I have a yamaha receiver and some speakers a friend of mine gave me. Well anyway for the most part its simple and I have a basic knowledge for this type of stuff. The only problem im having is the subwoofer output on the receiver is a plug type like a rca jack, the connection on the subwoofer is a two input and two output for speaker wire. How do I make this work?
