so do some poeple have more then 1 amp? like two 2 channel amps or something?oh yeah. Some people will have 7 monoblock amps. Or some will have a 3 channel amp that they use for the L C R speakers and a 2 channel that they bought later for their surrounds.
As for your other questions, there are so many different factors to those questions. Brand A amp may say 100w but that may be only with 1 channel driven whereas Brand B may say 100w but with all 5 channels driven at 20-20000hz. Brand B is going to be a more accurate number.
100w may be a lot, but that also depends on your speakers and room. What is the sensitivity of the speakers? How big is the room? If you have a very large room with low sensitivity speakers, 100w will not be nearly enough to "hurt your ears".
I'm not sure about theater speakers but don't forget they have to fill a room that is easily 20x bigger than any home theater. So that is pretty irrelevant.
