More of a PA question but thought you guys could help. I have a poweramp that says: Maximum power at 1% THD. midband, both channels driven 300w per channel into 8ohms. Continuous Sine Wave Average Output Power, both channels driven (rated power) 240w per channel into 8ohms from 40hz-20khz, with no more than .10% THD. What is it putting out at 8ohms 240 or 300? Would a pair of cabs rated at 300w RMS/600w continuous/1200w peak 8ohm be underpowerd?
