Chess, by now you may have had the third bottle of that wine and are on the floor, but if you can read this, we're talking about two different 4 ohm situations. You're correct that if sufficient voltage and therefore current was available more power(theoretically double) would be available into a 4 ohm speaker as compared to a 8 ohm speaker. However, I was speaking of the 4 ohm SWITCH POSITION which limits voltage and thereby current and allows for less maximum power to any given speaker than when in the 8 ohm position.
