I'm having my family room repainted. Now is the time to run wire behing the walls. I can patch holes and paint afterwards. I want to run wire from the TV/reciever area to potential speaker locations. I may not use those locations and I want to know if anyone can answer these questions: 1) What kind of wire should I run? 2) How can I terminate the wires at the wall so that it looks nice if not used (sort of like the cable tv outlet)?
