[QUOTE="Gauntlet, post: 111355, member: 545529"] For the former situation, it will be ok because you can play with the gains and get the amp to put out relatively what the RMS of the sub asks for. For the latter situation, it will not blow, it will simply sound like shit. Ralphus, do you know what distortion physically IS? It's an unwanted change ('distorted' change) in the waveform of the signal. So instead of the waveform being represented as a smooth curve/parabola, it will have some sort of anomaly in it - it may jet up too high and sound like a crackle, or it may jet down low and sound like a rumble, or it may even extend across and produce the note longer than its supposed to be produced. Hence, it is called distortion. It has no effect on whether the sub will blow, simply on how it sounds. You may think it sounds blown, but its not. If your theory was right, and too much power did not blow speakers, you could send a sub more than its rated power and have no problems. For example, you could take an Infinity Kappa Perfect 12" (350 RMS) and send 400 watts to it, and it will not blow, it will just get louder. I have experience in this, I had 2 of these subs and sent them 400 watts each with my Cadence Z9000, and suprise suprise, they blew. Granted some subwoofers you can send more than their rated power, but the most i've really seen is about 75-100 watts. Too much power will undoubtedly blow the subwoofer. Distortion will not.
