CONNECTING THE
SPEAKER WIRE
We recommend you use wire that is
color-coded or marked on one side.
Follow these steps to connect the
speaker to your receiver/amplifier.
1. Route the speaker wire from your
receiver/amplifier to the speaker.
Notes:
• Avoid routing the speaker wire
near electrical wire.
• Do not nail or staple the
speaker wire.
4. Connect the wire to the terminals
on the back of the speaker by
pressing the red terminal’s tab,
inserting one end of the marked
conductor, then releasing the tab.
Repeat this procedure to connect
the unmarked conductor to the
black terminal.
5. Using the wire’s color-coding or
marking as a guide, connect the
conductor that is connected to the
speaker’s red (+) termina l to your
amplifier/receiver’s positive (+)
terminal. Then c onnect the negative (–) conductor to your receiver/
amplifier’s negative (–) terminal.
2. Separate about 4 inches of
speaker wire at each end.
3. Using a wire stripper, remove
about
both ends of each conductor, then
twist the strands of each conductor.
