For a 15-inch subwoofer, it's generally recommended to use 12-gauge or 14-gauge speaker wire. The thicker 12-gauge wire is ideal for longer runs or higher power applications, as it reduces resistance and potential power loss. If the run is shorter and the power levels are lower, 14-gauge can be sufficient. Always consider the overall power handling and distance when selecting the appropriate gauge.
