Simple question?? how do I connect my Panasonic subwoofer to my denon receiver?

I had the same issue when my new sub had only an RCA type speaker terminal input, and the amps sub output was two banana clip types, same as the Denon amp has, I just bought a 4 foot male-end RCA cable, cut off one end, stripped the two wires (the inner/center most wire of the two that has the wrapping around it is the Pos+), I soldered 16 gague speaker wire to each end (the speaker wire with the white stripe I use as positve and so soldered that to the positive wire of the RCA cable), than separated each now connected wire and wrapped each one individually with electrical tape so they can't touch one anther and short out. Took an entire 4 minutes.
