All speakers require a small electrical charge to transmit the audio signal and deliver enough power to produce a satisfactory volume. Some speakers, such as small desktop models used with computers, contain built-in amplifiers to drive the units. Most full-size speakers, such as floor models for home theater or stereo, must be connected with speaker wire to an amplifier or receiver for power and to receive the audio signal. Connecting the speakers takes only a few minutes with simple tools.
Step 1
Place the speakers in the desired location, typically in pairs for a proper stereo setup.
Step 2
Cut a length of wire long enough to connect each speaker to the back of the amp or receiver, then strip about 1/2 inch of insulation from the two wires on each end.
Step 3
Lift the red and black clips on the back of each speaker to locate a small hole under each clip for inserting the wires. Insert the red wire in the hole beneath the red terminal. The other wire connects to the hole below the black terminal.
Step 4
Connect the other ends of the wire to the amp or receiver terminals in the same manner, taking care to hook up the wires from the left speaker to the two terminals for the left audio channel on the amp or receiver.
Plug the amp or receiver into an electrical outlet, play back a source signal, such as FM radio, on the receiver, and adjust the volume to a comfortable level for listening.
Tip
- Always connect the speaker wires to the correct polarity on the terminals, with the red wire attached to the positive terminal and the other wire, regardless of color, attached to the black terminal. Following this simple rule will virtually eliminate the risk of short circuits and crossed stereo signals.
Warning
- Do not plug the amp or receiver into the electricity until the speakers are connected.
