You begin with two 6-inch lengths of speaker wire, two RCA connectors, and a red, white, and black map pin.
Peel apart the two speaker wire pairs so you have four 6 inch lengths. Cut one length to 3 inches. Strip ~1/4 inch of insulation from each speaker wire end.
You will now install the ground wire on the white RCA connector.
Twist one end of the 3 inch length and one 6 inch length together, and insert wire into ground hole of connector.
Solder the connection and crimp the tabs.
Solder the black map pin to the other end of the 6 inch speaker wire length.
Solder another 6 inch speaker wire length to the RCA connector
Solder the white map pin to the other end of the 6 inch speaker wire.
Carefully thread the wires through the wire connector cover...
And screw it on!
Now install the red RCA connector cover through the 3 inch length.
And solder it to the ground connection on red RCA connector.
Insert the remaining 6 inch speaker wire length through the red connector cover.
And solder one end to the remaining solder lug on the RCA connector
Screw the RCA connector cover on the connector, and solder the red map pin on the remaining end of the 6 inch speaker wire. You are done with your electrode!
Now time to build your speaker. Cut off the last few inches of the speaker wires.
Strip the ends of the wires just a little bit.
Solder the wires to the 2-pin speaker connector.
Twist the two wires together.
Separate and wrap solder joints away from each other using electrical tape. Take care that the two solder joints do not touch.
