Clipping happens when you drive a transistor to a point where it wants to swing to a voltage higher than what your power supply can provide. It happens when you drive the amp with too much input signal.
It has NOTHING to do with how many watts your speaker can handle. You can literally instantly DESTROY a 500 watt speaker with a 10 watt badly designed amplifier with no clip protection, if it clips. That is because you are sending DC to the speaker and they absolutely hate that.
It is ALWAYS safer to use a higher power amplifier on a speaker but ALWAYS MUCH MORE dangerous to use an amplifier which is under powered for a speaker, especially if the amplifier has no anti clip circuitry.
