I have had my system for about 6 months and have never had a problem with it until the other week. I have a Soundstorm Force Amp rated at 1600 watts RMS at 2 ohms and a Pioneer Premier 12 inch dual voice coil 2 ohm sub rated at 1000 watts RMS. One day I was driving when all of the sudden my sub cut off. I pulled over and took a look at it and it was in protect mode so I just turned it off and let it cool thinking maybe it was overheated. I later tried turning it back on and it worked fine at low volume but when I turned it up at all it just went into protect mode. I hadnt changed any settings and its been doing it ever since. If I turn the volume back down or turn down my amp settings it comes back on but its uselessly quiet. Does anyone have any ideas about whats going on?
