Consider the location of the speakers and be sure to allow enough cable to reach each one. This includes the extra length needed for wiring the speaker before inserting it into the ceiling.
Preparing the cable wires
Speaker cable consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed) to identify it as positive. The other wire is negative.
Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully.
1.Strip approximately 1/2 in. (13 mm) of insulation from both wires.
2.Twist the bare end of each wire so loose strands will not touch across terminals.
Be sure to connect each wire to the proper speaker terminal, positive to positive (+) and negative to negative
Note: For information on installing cable, consult a professional electrician or audio/video installer, or look for reference books at a local home building retail store.
