Set up long cable runs with 250feet speaker wires. Thickness options include 12, 14, 16 and 18awg. 250ft speaker wires come with either 2 or 4 conductors. Choose a 4 wire 250 foot speaker cable and twine to lower the AWG. For outside speakers, stick with 250 feet CL2 rated cables for outdoor performance. This standard also applies when using 250feet wires to install in-wall speakers. Set up commercial speaker systems by buying 250foot speaker wires in bulk for cheap.
