I have a Carver 2 channel with 8 ohm speakers and tried to hook up 4 oihm Magnepans, problem the 8 ohm way over powers the out of the 4 ohm. If I put a resistor in line to match the 8 ohm speakers will the total volume be cut in half or will it still crank like it does with the 8 ohm speakers? Thanks for any help or answers, Joe
