What will I need I have 2 JL audio W7's powerd by 2 1000 Monoblock Amps with another 450/4 amp?

I have 3 amps 2 1000/1 and 1 450/4 with 0 guage wire and I upgraded my alternator to a 200amp alternator and I have 2 yellow top optima batteries But it still is not enough. My lights dim like crazy and I just blew my alternator. What would you suggest that I need so I can not worry about any problems and just listen to my system.
