Distortion is what causes heating of the voice coil and kills speakers, the higher the power of the amp the better regardless of the speaker rating as it will produce the required power for the desired volume level with less distortion.
The amount of power required for a speaker to produce a given sound level is determined by the efficiency of the speaker, and is independent of the amplifier. In other words if you have a 100 watt amp and a speaker is using an average of 15 watts to produce the desired sound level and you connect a 1000 watt amp and set the volume for the same sound level the speaker will still only be using 15 watts.
I have used home stereo speaker rated for 100 watts with a 500 watt per channel amp for years, it is not a concern
Great post. I learned stuff.
