I've been working on a 2x15 speaker cab for a little bit, and the time has come to wire up the jack. I have 2 Faital 15PR400s at 8 ohms each. I'm going to wire them in parallel making the cab 4 ohms. I also am not using any crossover of any kind. I want to have these running into a speakon 1/4 combo jack, but I have never used one of these jacks before. My question is: do I just wire both positive wires to the positive terminal and both negative wires to the negative terminal? (I attached a drawing to illustrate my question). Also, does it matter what gauge copper wire I use? I just have 16AWG here right now. Lastly, I could only find 2 styles of speakon 1/4 combo jacks. They appear to be the same, besides the the fact that one has a PCB mount and the other doesn't. One of the jacks talks about how it can accept a twist lock 1/4 cable... not sure what that means. But are there any differences between these two that I am missing?? 1) "Neutrik NLJ2MD-V speakON 1/4" Combo Connector 2-Pole Vertical PCB Mount" from www.parts-express.com! 2) "Neutrik NLJ2MD-H speakON 1/4" Combo Connector 2-Pole PCB Mount Horizontal" from www.parts-express.com!
