OK I vaguely understand. My problem is I will have a long run to my QS8 about 45-50 ft(possibly longer). I want to use 14 or 12g wire (Which is better? is this even correct?) my back surr wires are stuck through the sheet rock 16g 30-35 ft runs they are staying. The chart does not list max run for 6 ohms for runs longer than 37. What wire do I use with my long run qs8? thanks for your help.
