[QUOTE="T3mpest, post: 8137981, member: 560148"] It's an 8inch sub with a 2inch coil. They are designed to take power better than most subs of that size, but realize one thing.. The coil is still the same size. The glue may be better, but ultimately it's going to heat up as fast as ANY other 2inch coiled speaker, the only difference is, the heat gets away from the coil better.. That's probably why your feeling such a warm dustcap, that and a 40min run at even 5-600 watts is going to heat up a coil regardless. Your just expecting too much from the drivers, IMHO. If they aren't failing however, don't worry about it. Just like amps that tend to get very hot, if they aren't going into thermal protection, then the heatsink is just doing it's job. Lots of small higher ouput amps are like that, high power, small footprint, heatsink that could cook eggs in a pinch. In this case you have no thermal protection circuit, but you should smell before they give out, the fact you haven't is a good sign. People always say it takes power to make power, so saying things are getting too hot due to low voltage is a bit backwards. Really, a more correct statement would be he's running the amp hard enough to cause low voltage at the battery, due to the higher output of the amp. Again, not so much to do with clipping as it is the high voltage levels in the first place. IF that amp is drawing enough current to strain your electrical, it's also producing enough power to heat the subs up. IMHO, upgrade your electrical, and add a 3rd or 4th sub if space allows.
