Battery and alt upgrade

[Krypknots]

Looking to do the big three upgrade I think it is called and need some help on a new alt. and battery. Going to build system up to about 4000 watts rms all together. What should I get strength-wise for the alt and batt.?

For 4k I'd go with lithium. I'm happy with my hp40 battery and would recommend it. Biggest reputable alternator you can find for your vehicle. Be sure to read reviews before you buy an alternator.
