[. . . ] Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using banana plugs, connect them to the wires and then plug into the backs of the binding posts. The collars of the binding posts should be screwed in all the way (clockwise). If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. [. . . ]
