1 watt =87db
2 watts = 90db
4 watts = 93db
8 watts = 96db
16 watts = 99db
THX is 110db, ultra THX is 112db
A couple of things to keep in mind:
1-there's no crossover in the amp, just over a certain load, it starts switching out.
2-you could be playing in class A all day long at 5 watts which is fairly loud. However, if there is a dynamic peak the amp will automatically fall into class b and then back again. So, it should be seamless when switching.
There are really only 2 ways to know: The amp will lose some of its warmness & the amp will run much cooler. In class A, the circuits are running at peak all of the time. They have to dissipate the power somehow if you don't need the volume so it's given off in heat.
