Ok, in another thread that I posted too, I mentioned I had prewired coax for sub locations. Some one mentioned that a coax cable is the wrong cable to prewire for a sub. I thought it was fine. I'm using Quad-shielded RG6 and will be terminating in RCA plugs with a waterproof crimper from Parts Express. What are people's thoughts?? I still have the oppertunity to run something else before I put up the drywall.
