2.5 Output Wiring and Connectors

To drive distributed speaker systems designed to operate at 70V or 100V, connect to 
the corresponding output terminals.

JBL recommends using pre-built or professionally wired, high-quality, two-conductor, 
heavy gauge speaker wire. Speakers wires should be twisted cable, if possible. To 
prevent the possibility of short-circuits, the wires should be stripped back no greater 
than 6 mm (1/4 inch), see Figure 2.5.2.

Suggested below are guidelines to select the appropriate size of wire based on the 
distance from amplifier to speaker. Check with local code as this may vary.
