Cat, that's too bad, it looks like Murphy's Law reared it's head up over you on a late Sunday afternoon. Were you thinking of continuing to use those cables, or switching them out to something you're more a custom too, then saving them as spares.
I was going to use them if they were long enough, but one of them wasn't. One of the ends snapped right off, leaving just bare wires exposed. Oops. Similar problem with the other one. All's well now, cable-wise so-far. Just need to work on getting the subwoofer up and running, and getting all the speakers installed, which includes priming and painting some wood they will get mounted to.
