1) Connect the POSITIVE speaker terminals together with a piece of wire (Bob liked the 20ga wire we were issued for this)
2) Get a FEMALE to DOUBLE MALE RCA Y cord, connect red RCA to the end of the Y cord, and then connect the Y cord to the corresponding colors on your RCA inputs.
3) connect your speaker wires to either set of inputs, Bob said it didn't matter which ones you use.
Hope this helps,
