Anyone out there good at installing surround sound. I have something I need some help with. I am going to install surround sound up through a wall and into the attic and then down through the ceiling to speakers in the back corners of the room. Normally you are dealing with speaker wires that can be spliced and a plate installed on the wall that the receiver can plug into. Seeing that I don’t want to splice the wires that came with the bose radio a friend gave me I need to drill a 3/8 inch hole in the wall to run the speaker wire into the attic but then the wire itself is very thin and so the hole will have a fairly large gap around the wire going into the wall. Do I just putty and paint the hole or is there some kind of special plug that fits into the hole around the wire? Any ideas?
