correct. What i was trying to say is that a lot of people who use smaller amps are not happy with the sound output and therefore turn the gain up causing distortion and damage(cranking the gain). Obviously the power the sub recieves is dependent on the volume as well so saying that underpowering a sub damages it is like saying that turning the volume down damages it as well. However, it is better to underpower it than to overpower it, if you exceed the thermal limits of the sub then you are in trouble. That being said, the closer your are to the specs of the sub, the better it will sound (obviously)
