Actually, the speakers are not distorting at all... What you are hearing is 
the final amplifier inside the radio distorting... This happens to most head 
units when playing them at high volumes.... The speakers are just reproducing 
the distortion...  Underpowering a speaker will not cause distortion... (if 
this were true, then you would hear distortion when you are playing your 
radio at low volumes)...
Many companies that sell head units market them as 'high-power' claiming that 
their head unit will put out 35 x 4 (max rating)... but what the average 
consumer doesn't realize is that you should be looking at the RMS rating of 
the output power.. (which typically is less than 10 watts per channel)...  
They can make the claim of a 35 watt per channel output by how they measure 
the maximum rating... Typically it is only a peak for a fraction of a 
second...
