Making the connections
Preparing the speaker wire (not provided)
Speaker cord consists of two insulated wires. The insulation around one wire is striped,
collared, or ribbed. This marked wire is positive (+). The plain wire is negative (–). These
correspond to the red (+) and black (–) terminals on the back of the speaker, receiver, or
amplifier. Be sure to connect each wire to the proper terminal (positive to positive, negative
to negative).
Figure 14
Preparing the ends of each
wire
At the ends of each cord, strip approximately 1 ⁄
2
inch (1.3 cm) of insulation from both wires
(Figure 14). Next, twist the ends of each wire so there are no loose strands.

Unscrewing the hex knob
Connecting the speaker wire to the speakers
At the back of your speaker, unscrew the hex knobs on the terminal posts. This reveals a
small opening through each post (Figure 15). Using the wire guides, insert the marked wire
into the red (+) terminal. Then insert the plain wire into the black (–) terminal. Tighten the
knobs to secure the wires. See Figures 16A and 16B on page 10.
