What is the best gauge wire for car speakers?
When you replace or run new speaker wiring, we recommend using: 18-, 16-, or 14-gauge wires for speakers. 16-, 14-, or 12-gauge wires for subwoofers.
How many watts can 16 gauge speaker wire handle?
16 gauge wire shouldn’t be tasked with more than 15 amps (and 10 is better). Wattage (power) = volts * amps. Volts = amps * resistance (ohms). If we limit ourselves to 10 amps, that drops to 10*10*8= 800 watts.
Which wire is best for speakers?
Most of the best speaker wires are made from copper, since copper is a wonderful conductor of electricity. For the best quality wire, looking for something made with 100% copper is highly recommended.
