New to the game, suggestions?

Hey guys, got a new truck and taking out 3/4 of the rear seat. I want to do dual JL 13w7 and am leaning towards a fatboxusa competition series box. I don't really know any other box manufactures with a dual setup. I also would get two jL HD 1200 amps.

Will this suffice?

Also, need a bigger alternator, battery I assume.

Anything else you highly suggest I get with a setup like this? Brand of wiring etc? I want the best

 
I can help you here. Year make model of truck and motor. Also 0 gauge wire big 3. And agm batts What are trying to get from the new system ?
icustiomf your going with subs like that they don't deserve a prefab. you can get a custom box made for practically the same price.
