SO I'm playing around trying to adjust my speaker set-up in the living room tonight and I hear something in my sub box so I unscrew the speaker. Open it up and there are three balls inside courtesy of my children of course. Anyway I get them out and screw the speaker back in place. I hook everything up and turn the power to the sub on. Nothing I turn it off unplug it then try again all off a sudden I get this low electronic hum and a bad odor starts going form the amp. Like burning rubber. So I quickly turn it off which does nothing so I unplugged it. It is a BIC America 10" model D-1010R 160 watts. Any ideas? I didn't touch any of the wiring at all I just unscrewed it then screwed it back in.
