OK... I ordered my new head and have been doing a little preliminary reading. In the specs it claims that the output is 300 watts @ 8 ohms AND 300 watts @ 4 ohms. This, I don't understand... it flies in the face of everything I learned in electronics 101. I was under the impression that if your amp pumped out 300 watts @ 8 ohms it would put out 600 @ 4 ohms, 1200 @ 2 ohms, 2400 @ 1 ohm, etc., etc., etc. The limiting factor would be the amps minimum required load... in my case; 4 ohms. What am I not understanding????
