Also, here is another thought. I need 50 feet total length. If I have the majority of the length of cable coming to my speakers (40 ft) as 12 gauge, but then simply add 10 feet of 14 gauge (solder, crimp, etc) then the last 10 feet will be very flexible but at least the majority at 12 gauge has less resistance than if I do it all at 14 gauge, right??
