I have some extra speaker wire and I would like to try twisting the pair together. I have seen this explained on a website but the link no longer works. How excatly would this be done, is there is special technique to braiding the pairs together? I have some speakers that are biwirable and figured I would experiment since its not going to cost anything. I had been looking into some bi-wired speaker cable but is going to cost a lot for the length I need. The wire I have is 12 guage but the article I read they were using 14 guage and when combined became 11 guage. What guage would two 12's produce and are there any concerns with such a thick guage? Thanks.
