Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine. Its cost-effective and easy to work with.

Is speaker wire different from electrical wire?

The only difference is that speaker wire typically has clear outer insulation, while electrical wire might be black, brown, white or some other color. That similarity isnt an illusion; the wires are very much alike and can be used interchangeably in many circumstances.

Can speaker wire catch fire?

When dealing with electricity the potential for fire always exists. With speaker wire the threat level is very low, as the voltages involved are low, while amplifiers usually have protection circuits that will shut the amp down in the event of a short circuit.

Does speaker wire have to be copper?

Wire material Copper is the most widely used material for speaker cable due to its low cost and low resistance. However, copper does oxidise so it needs to be well covered and insulated.
