I have a finishing question. My brother in-law, who used to install HTs, and I prewired my HT during the construction of my house. He is not good about getting back to me with anything, so I thought I would ask anyone here. We prewired for subs in several areas with RG6 cable. How do you finish these out for use with subs? I want to try to get some things done before he comes back up to help me out.
