Biggest battery under the hood for a 2001 Buick Century

[Jerm1400]

I have a 2001 Buick century with two American bass tnt 12's running off of a belva bb2000d, a xs power d975 in the trunk and a lil everstart battery in the front. I have done the big 3 with 2 gauge wire and will be switching to 0 gauge soon and upgrading to a q1-2200d. At full tilt my voltage drops to 12.5. I was thinking about putting a xs power d3400 under the hood & a d3100 in the trunk but the prices are kinda turning me away. I see people speak highly of Deka batteries but I never ran them and I don't know which is the biggest I can fit under the hood and are the optima batteries worth it?

A battery wont help that. You need to make sure your gain and ground is right. If it is and dropping that far you need a bigger alternator

If you are looking for great power at a good price, these are friggen fantastic, just got one a week ago, running 4k and it helped a lot.

http://www.caraudio.com/forums/electrical-wiring-classifieds/609203-fs-c-d-ups-12-350-batteries-93ah.html This is a great battery at a great deal much much better then optimas can ever be, not quite as crazy as an xs power but close enough at 1/3 the price you can get two or 3 and it'll be a sh*t ton more performance for the money.

Dekas are made by east penn, autozone's duracell platinum, o reillys' super start platinum. I used a G31 from autozone they work fine (c&d works better to me though)

Odyssey batteries are close to the same league as xs power, an alternative to them are sears diehard platinum, same battery as an odyssey.

A battery will not keep you over 13v.......... If he stuck a good DMM on the +/- I bet it will show 10s

I have no doubt in that but 2 new batts on a stock alt on the power for daily is fine ..no way id shell out cash for a ho alt

Why not? Its going to cost the same in the long run and be much better

Now when he plans on going over 3k fine but for now no sense in dropping dough on a alt..i have lots of buddies who run 2-2500 on that battery setup for years

You can get a decent 200 amp alt for $400. All those batteries are going to do is creat a load, they are going to get very discharged and keep discharging to the point the amp will fail and cause vehicle issues. If he is dropping that far now adding a battery will not fix it because you know it is really dropping way more. Why pay for a 2000 watt amp if you are only getting 1000 watts since you cant feed it? It makes no sence to me, just get a 1000 watt amp to begin with

I actually have the duracell group 31 agm and it really does not impress me as the C&D. Gonna use both of them but I tested them each individually because I like to put things up against each other. Got less voltage drop with the C&d on a prolonged burp, both batteries charged with a trickle charger.

The ground is sanded and bolted to the strut mount and I probably do have to gain up too high because the amp does get a lil toasty but it never shuts off tho

Most ppl dont have the dough to drop all that at once

improper gain will kill voltage
