The banana plug comes apart into three pieces – the screw end, cylinder and male end.

Strip approximately ¾” of insulation from your speaker wire (this particular plug can accept wire from 26ga to 12ga).

Insert bare speaker wire through hole in the center of the screw end. There should be 1/8” – ¼” of wire visible. Be sure to place the cylinder back into the male end if you haven’t already.

This picture is for reference only: On the inside of the banana plug – the wire forms a fan configuration which makes an excellent contact with the cylinder which is what makes contact with the male end.

Screw the back into the male end while pushing in on the wire. When finished – be sure that the wire can not be pulled back out and that it is seated properly.

Strip 3/8” of insulation from your speaker wire (this particular pin can accept wire from 26ga to 12ga).
