What gauge speaker wire should I use for my home audio setup?

I work at a best buy and this is what i tell customers. When you're dealing with wiring speaker systems the gauge of the wire only really matters when exceed a certain distance because the bigger gauge number the wider the cable. So you want a larger gauge when your dealing with longer distances. A general rule of thumb I use is 50 feat for a 2 gauge difference. If your dealing with anything less than 50 feat 16+ gauge will do just fine. Hope this helps! Good luck!
