Factory system help

[eric78702 10+ year member]

I am getting 4 sa 12's and I was wondering if it would be okay to run a 2500 watt amp on a factory 95 amp alt with an upgraded battery under the hood with one or maybe two batters in the back if possible? I don't know what batteries to put in the back so suggestion would be nice. Thanks.

theres a guy in killeen called the battery guy......he sells factory seconds big sprinter batteries...real cheap but bad azz batteries...I currently have three plus stock up front running an aq 2200 and my lights dont even think about dimming and my voltage is VERY stable.......pm me if you want the number I promise your not gonna find a better deal on batteries
