There are two schools of thought on clipping.
1) The clipped waveform causes a square-wave like waveshape which has an extreme amount of distortion that causes drivers to fry.
2) The clipped waveform has nothing to do with distortion but instead increased power dissipated by the device (square wave has greater area under the curve so to speak).
In any case, many say to get amps larger than the rating of the speakers. If you are 'pushing' your amp you need a bigger amp, just like if you were pushing your speakers you need bigger speakers. How big the amp is, though, is also a function of how efficient your speakers are. If you have a horn system you might never clip a 30W amp, but you could clip a 300W amp frequently on 86db/octave speakers.
So, many say that a 200W/ch. amp is LESS likely to blow 100W speakers than a 50W amp is and in general they are correct, so long as one knows how to avoid exceeding the thermal or excusion limits of the speaker.
Theoretically, you can have an amp too big, too small and "just right" - much like Goldilocks and her porridge experience in the bears house.
Cheers,
Presto
