Deck railing or table Installing Your 251TM Speakers B. 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 ⁄1 inch (1.3 cm) 2 At the ends of each cord, strip approximately ⁄1 inch (1.3 cm) of insulation from both wires 2 (Figure 14). Next, twist the ends of each wire so there are no loose strands.
