Understanding WPC (watts per channel)

[busterbrown]

I am 48 years and finally figured out why my receivers over the years
have gone into protect mode or shut down. When you look at the specs on
a receiver you look at wpc, let's say 110, that's 110 by 2 ch driven or 2 speakers, that's 220 watts that the receiver can drive period !. If your
watching 5.1 surround thats 5 channels driven the receiver is pushing
42 wpc, depending on volume and the loudness of a particular scene is when
the receiver would go into protect mode. let's say you have volume at 10,
the front speaker might be pulling 35 watts, but there is a explosion or
airplane crashing or whatever and that scene causes the speaker to pull
50 watts then the speaker distorts the receiver clip and you need new speakers
I believe the industry is not as misleading as they are not forthright.
Before there was surround sound there was stereo (2 ch) and they would
say 110 wpc, today it is the same and it's true, but the amp makers
should have to add 5,7,9 wpc:

110 wpc x 2----42 wpc x 5----30 wpc x 7---23 wpc x 9
