I recently blew a Red Fang (30 watts) that I was using in my Mazerati combo (32 watts). I never really pushed the speaker that hard, so I was a little surprised that it blew. So perhaps an expensive lesson was learned. Is there a rule of thumb for matching a speaker wattage to an amp? I did realize that I was "close" using the 30 watt RF in my amp, but I figured I wouldn't approach the danger zone unless I really cranked it.
