Here goes. The setup of my rear surrounds (and my fiance's penchant for aesthetics over sound) recently required me to wire my rear speakers using AR's 18 ga MicroFlat. This stuff has an adhesive backing and can be stuck to the wall and painted over so that it is almost unseeable. I took someone's advice from this board and ran 12 ga soundking all the way to the base of the rear wall and only used about 4.5 feet of the Microflat for each speaker to run it up the wall. My question is, given that this wire is not made up of thin copper strands like normal cable, but is instead one continuous thin, wide flat piece of copper for each polarity, would it be worth my while (sound quality-wise) to use 2 separate runs of the Microflat (one right on top of the other) for each speaker, twisting the +/- ends together on each to give a lower gauge? So the + side of the rear left for example would have one cable all to itself and the - side another. Does this make any sense? Is it a good idea? Is there a technical term for this?
