I hope I will never blow aything in my system ! My bass amp is never really hot, and the sub neither (a BTL N2 on a 1500 w amp). A friend of mine is running a Sundown NS-1 (@ 2 Ohms) on a fi btl N2 : after a loud listening session, the sub and amp are not even hot !!! You can say, by touch, that they were playing, but you can never guess they were playing so loud and for so long. People are, first, impressed with the output and the sound quality, and then, when they touch the equipment, most do not understand how it can be so cold !!! I live in the Caribbeans : hot weather all year-long, and lots of rain too ! We both have no DD-1, no O'scope, only our ears. When it sound weird, turn it down or back the gain down, and that's it. Good luck.
