sorry I did'nt word everything proper.lets go one more time,MORE current is required from my amp when driving the m-80's to produce the same power as the m-60's.as LESS current is needed for the m-60's to create the same power as of the m-80's.so just because onkyo stamps high current on there stuff dosn't mean so. the funny thing is that the receiver would trip up without getting hot at all and if I wanted to I could almost trip the protect mode almost instantly. is it possable that the m-80's might be dipping down below the 4 ohm rateing?it all comes down to ohm's is the measurement of resistance,less resistance equals more current flow,equals more current demand from the amp.or should I say more current flow threw the amp's power supply?
