I was just jamming to some music at about 30 volume on the receiver and the sub was hitting hard. It started making a popping and crackling sound I immediately stopped the music. I then ran over to it and turned the gain to very low and started the music back up. Now I have absolutely no sound out of the sub not even a hum. I pulled the sub out of the box and verified the connections were fine. There isn't a burnt smell on either the receiver or amp. Any ideas what to test? Where to start? Whats a guess on whats wrong?
The amp still has a green light while turned on. And the receiver appears to be fine. Did the plate amp just blow?

speaker fuse?
power supply/AC line fuse?
rail fuses?
btw "30" on your volume control has absolutely no meaning in terms of how loud it was or how close to clipping or beyond you were at the time...

you can check the woofer coil(s) with a AA 1-1/2 volt or 9 volt battery; disconnect the speaker wires from the amp and just touch/connect the battery for a split second, the speaker should give a good push.
Also, I keep a speaker or two that are ready to be trashed, just to test an amplifier in situations like this. If the speaker coil cooks in a split second, bad news, but no harm done.
