What are you talking about.
Speakers blow when there is too much power appplied to them. A speaker has a maximum power ratting.
Watt is a measurment of power. power is a ratio of current and votlage. RMS - root mean squared is a method of averaging a waveform. W rms = Wp / sqrt2
A speaker will blow when there is too much wattage running to them.

ALthough you are correct, it is actually EASIER to destroy a speaker by underpowering it. In a Car Modificatiobn magazine, they tested subwoofers to destruction, and many of them could take double the RMS power that the manufacturers said. Higher quality makes could even take TRIPLE the power for a good five minutes. (ALpine Type S RMS was 300W, but could handle 900W RMS!)
By giving a 300w RMS sub an amp that can only dish out 100W RMS, and you turn up the volume. The consequent power that the sub should produce would be consistent with its power rating. Say for example you turn the volume up to the 100%. The sub will try and also give 100% by trying to recreate the sound signal it has been given. However, since the amp only gives 100W, and the sub is trying to reproduce a volume equivalent to the power that 300W will give it, the sound will distort, indicating that the voice coils are being overworked and stressed. They will burn out...not in the sense that they've exploded (lol) but in the sense that they're "tired". imagine an athelete who cannot continue running in a marathon because they've got no energy. compare that to the voicecoil, except that it will not recover. If you run a system like this for a short time, you will find that, even at low volumes, the sound will still be distorted, as if it were at high levels, due to the voice coils being useless
