To determine the appropriate wire size for an 800-watt amp, you need to consider the current draw and the length of the wire run. For an 800-watt amplifier running on a 12-volt system, you might expect around 67 amps of current. Typically, for up to 20 feet, a 4-gauge wire would be suitable, but always consult the amplifier's manual and use a wire gauge chart to ensure safety and efficiency for your specific setup.
