I'm hooking up a couple of small speakers (3w max each) outside, and I have a small run in my house from inside to out that was done with ethernet cable. There's no way I can pull speaker wire through, I need to use the ethernet for about 15 feet. I'll run heavy gauge speaker wire from the amplifier to ethernet cable, and then speaker to ethernet cable (both those runs are short, 5 feet or so).
What is the best way to use the ethernet cable (23 gauge cat6)?
Should I join each twisted pair together and treat it as 4 wires (one each for positive and negative times 2 speakers)?
Should I take one wire from two pairs (eg white-green, white-orange together are positive for one speaker, green and orange are negative)?
Should I just use two twisted pairs total and leave the others unused?
I know I need to keep the resistance down but I'm not sure of any capacitive effects are going to interfere, or what's best overall.
