Here is a good article from an installer goes through an analysis of power requirements, RMS, and sizing.
I plugged my system into a calculator and discussed that in this post
1) Some questions to ask:
What are your listening habits?
Do you play it loud?
Do you have a SPL meter to measure how loud?
What are your speakers?
Can we find some impedance and phase measurements?
2) Plug the measured efficiency rating into a power calculator
If you have you have a speaker with a combination of low impedance and challenging phase angles, then a lot of heat will be disappated by the transitors when driven hard.
There have been posts byThiel (90DB efficiency) owners with AVR's that shutdown even though they state that the volume was moderate.
No telling what moderate means.
Common sense can also be applied. Obviously, you probably should consider an amp for full range speaker costing thousands of dollars.
Especially, when you can buy a hell of a lot of amp for a fraction of the cost.
