Monster 80 ft. 16 ga. 2 conductor UL Speaker Cable - CRS162RCL80 by Monster Cable

When running audio cables inside a wall, it pays to install the best cable possible you probably don't want to do the job twice. The sonic degradation from conventional cables can be significant, especially over long in-wall cable runs. Monster's in-wall speaker cables use ultra-fine, high-purity copper strands for increased flexibility and maximum conductivity, plus twisted-pair construction to minimize problems associated with radio frequency and electromagnetic interference. Their special low-friction jacket makes them very easy to pull through walls.These cables are CL3/FT4 rated, and they comply with the national electrical code for in-wall installations (check with your local building/electrical inspector regarding the code in your area).
