With M22s or any other 8 ohm speaker you normally wire the two centers in parallel.... wires go from receiver to one speaker, then continue (red to red, black to black) to the second speaker.

With 6 or 4 ohm speakers you would probably want to wire them in series instead to keep the total impedence within a range that your receiver/amp could handle.
