I have been under the impression that speakers need for their amps to supply at least their minimum power requirements. If they don't, then they can get severely clipped waves and end up blowing the speakers.

From research and speaking to car stereo experts around here, I would partially agree. If you don't supply at least the minimum power requirements, then the speaker is not faithfully reproducing the sound (distortion or clipping). But, I just don't see how you could blow a speaker by supplying it with too little power.

Of course, I could way off base as well.
