[QUOTE="Lasherž, post: 8711514, member: 679555"] As Jeff said, it was definitely clipping. You should never set gains without at the very least a clipping indicator light, low tones it's pretty hard to hear clips. What you're probably expecting it to sound like is max excursion which you can definitely hear. The proper way to set gains is with test tones, a multimeter or oscilloscope, and no subwoofer attached. Amps will gladly produce more power than their rating all the way up until the waveform becomes square if you push them, but that's bad for the amp (generates a lot of heat) and especially bad for the woofer (low cone movement and high power will melt coils, which is what happened here). A lot of people seem to do this thing where they say "the gain was only turned up half way" but misunderstand that a gain knob isn't a volume knob, if you feed your amplifier a 10v pre-out signal you could very well damage equipment going 1/5 of the way up.
