Since the center amps in a 7100 will have higher exposure to heat. Has anyone tried, and if so, what was the result of connecting lower ohm speakers to the outside amps?

i.e. If your front speakers are 4 ohms and the rest 8, I would think your amp would run cooler if the 4 ohm speakers were connected to the farthest (outside) left and right amps..

Just a thought..
