help choosing xs power battery

[Reed Farrar]

hey i have 2 e10 sundown subs wired to a hifonics BRZ 1200 watt amp and my voltage goes down to the 12s so i have finally decided to get a second battery for my car and later on maybe get a HO alternator. right now i have a stock 90 amp alternator on my 2001 oldsmobile alero. i have the big 3 done in 0 gauge , the wires running to my amp are also 0 gauge. i have been looking at the D925, D975, D1200. any input on what battery you think would work best for my system or maybe even just to get a HO alternator instead. here are some pics of my battery.

id change that napa batt out first.

[Reed Farrar]

you think it would be better to just get a bigger battery for just the front?

[_94fleet]

that does not look like a agm batt so if you add a xs power you are already mixing batt types. so yes change that out. whatever fits. preferably the biggest one that will fit.

X2 on what he said. Replace that, get biggest that'll fit.

lol, not kidding, that's legit advice. It'll help you a lot. Then if it drops still? (Probably will, but not to that extent), either another batt OR h/o alt... I'd do alt then 2nd batt but... that's me.

Get two of the same battery so they are not pulling and pushing on each other as much. I would say two 975s would be wonderful. I run the same batteries for my 2k set up.

alright i appreciate the help. ill prob just get one big xs battery for the front and go from there if it still drops

[Reed Farrar]

so i was looking at the 3400 but then measured and there is no way thats gonna fit. so i guess im gonna have to get two smaller batterys

[Reed Farrar]

all of the xs batterys i can find are to tall to fit in the regular spot for my battery. and suggestions?

I only see the big two!
