I have an M&K MX-100 that is in non-working order. I have a thread about the starting problem, but know I have a new problem. It was proposed the woofer or woofers were damaged during an intense passage in Resident Evil: Apocalypse, causing them to be shorted. When I replaced the amplifier fuses the amp protect fuses blew, but as far as I can tell no cinged circuits, no smells, and no smoke. What confounds me is when I plugged it in after replacing the fuses the woofer made a noise that I can only describe as a loud hum untill I unplugged it because I saw that the fuses were glowing. Under normal circumstances the sub makes a thump noise, and of coarse the fuses don't blow. Also when I unplug, when the sub still worked, it takes a few moments before releasing, instantaneously, the stored energy in the caps and makes the sound of a large nail being pulled out of dry wood, like a moaning creek, very unpleasant sound. So are they the problem, I am not sure. How do I test the woofers to see if they are indeed shorted?
