How to Hook Up Speaker Wire to Speakers

By James Clark

Audio speakers connect to a signal source with a speaker wire split into two strands for the positive and negative terminals. Speaker wire is typically coded so each of the two wires is a different color to make connections to the terminals easier. By hooking up the wires to the correct terminals, proper stereo sound can be heard from the source signal, such as a CD player hooked up to the stereo receiver that sends the audio out to the speakers.

Things You'll Need

  • Wire strippers

Step 1

Turn off the stereo receiver before connecting the speakers, to prevent a potential short circuit that could occur if the two wires touch accidentally. This can burn out the amplifiers in the receiver.

Step 2

Clip a length of speaker wire long enough to connect between the stereo receiver and the speaker, then strip away about 1/2 inch of insulation from the two wire strands on each end.

Step 3

Twist the strands for each wire color together with the thumb and index finger to form two wrapped wires, typically a red wire and a silver wire.

Step 4

Lift the two spring clips on the back of the speaker to reveal two holes. The red wire inserts in the hole below the red (positive) spring clip. The other wire inserts in the hole below the black (negative) spring clip. Release the clips to secure the wires to the speaker terminals.

Step 5

Connect the wires on the other end to the stereo receiver in the same manner, matching the red wire to the red terminal.
