Speaker Wire Gauge Guide
You should use 16 AWG (1.3 through 1.5 mm
2
) fully-tinned copper speaker wire for most installations. You
can use these tables to determine if you need to use a larger gauge of wire. These tables account for terminal
connection resistance.
NOTE: If you are using aluminum wire, you should use a wire two gauges larger than the gauge listed below to
compensate for a potential voltage drop due to the wire material.
4 Ohm Load (1 Speaker)
Distance between the amplifier and speaker
Wire gauge
From 0 to 28 ft. (from 0 to 8.5 m)
16 AWG (1.3 through 1.5 mm
2
)
From 28 to 69 ft. (from 8.5 to 21 m)
12 AWG (3 through 4 mm
2
)
2 Ohm Load (2 Speakers in Parallel)
Distance between the amplifier and speaker
Wire gauge
From 0 to 14 ft. (from 0 to 4 m)
16 AWG (1.3 through 1.5 mm
2
)
From 14 to 35 ft. (from 4 to 10.5 m)
12 AWG (3 through 4 mm
2
)
You can purchase the recommended speaker wire from your Fusion
®
or Garmin

dealer.
