I am trying to wire my brothers cabinet so it is 4ohm mono. It has 4x12 16ohm speakers. Once I have all the speakers wired in parallel, I will have 1 wire that is pos and another that is neg. My problem is figuring out what to do with them. The rear panel of the cab has four wires: 1-ohm selector, 2-out, 3-in(left), 4-in(right). He is currently plugged into the left in of the cab. Which of these four wires do I use? And what do I do with the remaining? The amp was wired this way but kept shutting off. The four speakrs were paired off, and the negs and pos of each pair were connected, then it had 1- going to a neg of a speaker, 2- to a positve, 3- to a pos, and 4- to a neg, all seperate speakers. I really don't think this was correct. or am I wrong?
