I was just watching Resident Evil: Apocolypse at my usual volume, which is sort of high. The opening segment were they do a shift from above ground suburbs to one of the entrances to the hive, there is some heavy bass, the frequency is so low I can count how many times a second the woofer moves back and forth. The excersion is very high, for the sub and the front speakers. At the volume when it happened the Carver amp went into protect mode and the sub did something awfull. About 4 seconds after the tones started the voice coil locked up to the back of the magnet structure, I know because the surrounds were flexing in plain view and I heard a pop noise when it slapped up against the magnet structure. At this point the M&K had already disconnected power and I beleive the capacitors were releasing the remainder of their stored energy. Now the bad part. The Carver amp turned back on, the M&K did not. I tried unpluging it and plugging it back in, even though a sub this old wouldn't have a reset feature I figured I would try any way. I also checked the in line fuse, which appears to be fine, but I am not sure. I then took the amp plate off and looked at the internal fuses, there are two, and they also seem fine. The internal connections to the power supply were very warm and the power supply was steaming hot, it burnt my finger a little when I touched it. The transistor was cool to the touch. Note that the M&K doesn't have an auto shut off and I leave it on all the time, because if I unplug it, the only way to turn it off, it dumps all remainder energy the caps are holding instantaneously after about 30 seconds of being unplugged making another terrible sound. Does anyone know what went wrong here? Is it possible for the fuses to be damaged without actually appearing disconnected, like slight discolorations? Someone please help.
