The before amp I blow the voice coils of it and I thought that it supposed to protect itself but it did not. It was kind of my fault that I wired it up using one OHM and it over powered without heating. I learned my lesson and this amp works better and louder and cleaner. The problem that one person had was that the person did not set the amp up because I had the same problem with it turning off after one song. If you set it right it will last a really long time without even heating and still pounding hard. I even was able to set it so that my lights don't dim when it is pounding hard because I don't have a capacitor yet. I love my new amp and how it is smaller than the other one I had. So be careful and follow instructions and remember to wire up the amp right and set it right to make it last longer. At almost max volume, I believe like 75% this thing was shacking everything in my garage and house and my garage is not attached to my house there is a 15' difference between my house and garage. For future reference don't play two amps without a capacitor for long because it will try to kill your car because of the overload on the Alternator. This is only at peak performance of the amps. So now I am running a 400 watt Kenwood four channel amp powering four 60 watt Kenwood speakers and 1000 watts Kenwood duel mono amp powering two 500 watts 12" subs and no overheating if set right.
