Alright, this is probably a really dumb question.....but I figure it'd be even dumber to think I know the answer already and then to fry my amp. I've changed speakers out many times before, but the wires have always been colored. I just got an empty 1x12 cab with two wires from the jack, and they're the same color, and braided together. Can anyone explian to me how to tell from where they're soldered to the jack which one is positive and which one is negative? Thanks again, and please forgive my stupidity if it makes no difference in a one speaker setup.
