I need advice on how to run speaker wire in my walls and what gauge to use. I was planning to use a paintable flat wire speaker (16 gauge) but I found that the paint did not adhere to the speaker jacket very well, even after two coats of primer. Now I'm stuck of what to use for my 3 surround speakers. I was thinking of running the wire behind the base boards then up to the speakers behind the wall and out through a little hole to the speaker. Thanks in advance.
