For longer wire runs, 300ft speaker cables come in handy. They can be found in 12awg, 14awg, 16awg and 18awg thicknesses. The 4 wire 300foot speaker cable can be twined to reduce its thickness while increasing audio quality. When installing speakers outside, stick with a CL2 rated 300 foot speaker wire for performance and safety reasons. CL2 rated 300feet in-wall speaker wires are here - and you can order them in bulk too.
