Clipping is the term for the graphical indication (on an oscilloscope) of the waveform of the signal (music) being deformed because the amplifier has reached and exceeded its maximum power. Said a simpler way, it's the product of any ampifier stage simply running out of power. The waveform squashes--deforms--and the sound quality then varies from not good to absolutely horrible depending on degree of clipping.
Clipping produces, generally, highly distorted sound with too much high-frequency distortion--again, depending on degree of overdrive--that CAN damage speakers.
If you're seeing your clipping indicator blink just occasionally, probably you need do nothing. If you see it blinking frequently, you need to turn down the level several decibels--unless you want to damage a speaker. Of course, the solution to this entire problem is buying more power--and not just a little more. If you're seeing the indicator blink often, you need probably at least 3dB and maybe as much as 6dB more power; 3dB is double what you have and 6dB is 4 times what you have.
