You should go along the floor and tuck the wires between the carpeting and the molding. If there are no doors in between, you will have a very neat and professional looking install.
I saw something on QVC the other night called Museum Gel. It's reusable and holds up to 30-40lbs of weight. They showed it being used for nicknacks, but it should work for a lot of other uses. I'm going to order a jar and see how it works out. I can't do anything pretty here. I'm just going up the back wall, across the ceiling and down the back wall. You'll be able to see the wires really easlily, but I don't mind. It's going to sound great.
How about running wire for somebody that brick walls with plain cement grouting? Does anybody have a suggestion? Or do you feel that glue gun fix will do it? Thanks.
