A basic rule of thumb is this. For up to 500 watts RMS, 8 gauge is sufficient. In the 500 – 1000 watt RMS range, you want to run 4 gauge. From 1000 – 1500 watts RMS you should be running 2 gauge.

Moreover, How many amps can 8 gauge wire handle at 12 volts?
Secondly, Can 8 gauge wire handle 40 amps?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”May 28, 2020
Simply so, How many amps can 8 gauge wire handle?
40 amps
What size wire do I need for 40 amps?
40 AMP Wire Size For a maximum of 40 amps, you’ll need a wire gauge of 8. Many electric cooking appliances require 40 amps such as electric cooktops.

What gauge wire is best for car audio?
For most cases using home or car speakers (not subwoofers) 18 gauge (18AWG) is fine. 18AWG wire is good for about 50W for 4 ohm (car) speakers and 100W for 8 ohm (home stereo) speakers. For higher power systems or longer lengths, 16 gauge is a great choice.
