The battery analogy was more of a joke but it sorta had a point. My guess is the 28 gauge wire would melt and with the wrench the battery would melt. But I am not about to try it. The point is where do you want your power to be used? By the wire or the speaker? The rest of what you said in your last post I totally agree with. I am also not totally sold that speaker wire that has more strands is better then less. It seems to me a 14 gauge solid wire would have less effect on high frequencies then a multi stranded wire. Of course it is not practical to pull solid wire through walls etc.
