Power Upgrades for System

[napalm 10+ year member]

I have had some equipment installed recently in 2005 Altima, but I contemplating adding my two sub and amps to complete the system. I currently have (2) Xtant 1.1's and Xtant 2.2 handling my components and and rear door speakers. The two 1.1 draw about 10A/ea. and 2.2 is about 30A. My stock alternator output is 110A.

Here is my dilemma. My two JL 500/1 draw potentially 50A/ea, but I have checked around and the cost of buying a H.O. Output alternator is around $500-600 for an additional 40A. Not really worth it to me. Many people have suggested using a battery w/isolator, also using a 12-Farad capacitor, and batcaps.

Can someone please set me straight. I really don't know what I should do.

Big 3 and I would say a optima battery should be good.

100 amp current draw at max? do you have a problem with dimming or something like that? i wouldn't think you would.

also.. you wouldn't be interested in getting rid of those 1.1's eh?
