Dose anyone knows what's wrong with my amplifier?

couple days ago, I tried to show off my amplifier to some chicks, so I gained up volume on the amplifier and subwoofer, than my subwoofer playing the beats constant. Do to that point I have shot off the system. Long story short, I waited for a day and turned back on the subwoofer have no problems at all, do to that point I gained the volume again, than my amplifier is completely shots off, it wouldn't turn back on. I tried re-instill it wouldn't work, I checked my power on my amp and battery is stable at 35.8 bats. So, I assume is not my power problems, I checked my fuse is not blown, which lead to only one concert 'did the amplifier shot down because to do the heat?' but it has cooling technology built into it. or can I blow the amp out? I had this amplifier running on 1500 watts RMS, which is 1500 watts one Ohm stable amplifier, I have never running in to this kind of problem, or should I change a new battery to see what's going on? the amplifier is MTX audio Thunder elite 1501D and the subs are 2 MTX audio TS8512 at 4 Ohm. I am pretty sure that subs have no problems, they still going in and out pretty flexible when I pushing the center of the woofer in. So can you give me some info on what's is really going on with my systems? thanks for reading all this and helping me out.
