| Type in the power output of the amp, the impedance of the cabinet or speaker, and the length of the speaker cable you want to run. The answer will be the gauge of the stranded wire you should use for the speaker cable. This calculator is limited to 500 watts, greater than 2 ohms, and cable lengths not to exceed 20 feet. The gauges we most commonly use are even numbers, such as 18, 16, 14, etc. If you get an answer that is
odd, such as 17, 19, etc., use the next lower even number. For instance, if the answer is 19, you would use 18 gauge wire. |
