I'm working on 2 sealed UM18s that I want to power off of a Crown XLS5000, 1600x2 at 4 ohms. I was planning on internally wiring with 14AWG, mostly because its flexible, but should I be using a thicker gauge? Parts express is telling me 10AWG. Its only about 30" so I figured 14AWG would be sufficient. What do you guys think? I want to do it right the first time so if 14AWG isn't optimal I'll go bigger.
