What car battery is best for a 1200 watt amp with an 1100 watt subwoofer?

I have a 1983 customized blazer. Its got a new 350hp V8 engine. But the battery sucks, so i was wondering whats a good car battery type that can hold that much power with out being dead all the time. Or hoping that the car starts every time i stop at walmart. So please help
