Big 3 + Watts ?

I'm planning to run a pa3000d with a 10" icon d2.

My question is, can i use 1/0 for the big 3 and use 4 awg for power/ground to the amp from battery?

I have an interstate battery under the hood and i think a 90 amp alt. I think its also going out on me.....how do i check?

I would use at least 1/0 to the amp as well as the Big3.
