What battery's should i buy?

[Dragonsyph]

I see alot of people with the d3100 XS, some some with d3400. If i say got 1 d3100, would you guys put it in back, or replace stock bat with it?

Or even the d7500 above. But thats like what 1000 dollars.

I just wanna know for sure before spending 500 dollars on a damn battery 8(

I plan to get another amp for the sub for 5000rms, and if i ever get enough cash, 2 18"s with 4 2500amps. But thats probably over a year away.

Haven't tried the big name brand batteries but I am running a Napa Legend AGM group 34 on a t1500bdcp and t1000-4 with a stock alternator (I have a singer hairpin just need a belt) and I can say that this battery is kicking ass.

if budget is an issue, I second this. the Legend's are very nice for their price.

but xs power ftmfw

I can run full tilt for about a minute before I dip below 12v and then I back off and let it recover... I REALLY need to get my alternator installed. On my stock battery I was about 3 hard bass hits at 3/4 volume before I dipped below 12v so it's a huge difference for me.
