Correct Speaker Polarity is Important
Polarity refers to + and – connections. Speaker wires are coded with printing or a ridge on the insulation on one of the leads so you know which lead was connected to the + and – terminals at the other end. This coding will help you keep the + and - polarity consistent for both channels.
Speaker Wire Length and Gauge (thickness)
When selecting speaker wire, follow these guidelines:
•Keep the length of your speaker wire as short as possible
•Use the thickest wire practical. For lengths greater than 50 feet, use speaker wire with an AWG (gauge) of 14 or lower. The smaller the AWG, the thicker the wire.
•Do not use speaker wire that is thinner than 16 AWG.
