If you're wiring for stereo the plug has 3 parts tip, ring, sleeve. Wire one speaker to the tip connection and ground connection. Wire the other speaker to ring connection and ground connection. Now you have stereo speakers. If you're wanting to wire for mono use one mono plug per speaker. As long as the speakers you are using are marked 4 or 8 ohms you will have no problem with matching the impedance. If they are less or more I wouldn't us them since they may overload the amp. If I've left out anything important someone will soon add or correct us. Good luck.
