2 or 3 battery's better?

[Mike Boots]

I used the power calculator and they recommend 3x khc2400 (7200 total) but for around the same price should I go with 2x khc3800 (7600 total)?

If it matters I'm gonna be using 2x 2500 rms kicker zx amps and a 1500 kicker zx.

(typo on the topic batteries)

either will work, but i hope you have a high output alternator in the 250-300a range. because you need more than just batteries, takes power to make power. I personally would do 4 of the 2400's, or 3 of the 3800's with a +250a alternator.

So would the bigger total / less batteries be better? Might even do xs power d7500 if thats the case.. and maybe a smaller battery as a backup?

I agree with chevy boy. A HO is a definite, what vehicle? Big 3? What wire? What subs? Multiple things need to be considered. If you are getting 3-4 batts then the biggest alt you can fit is my opinion. Thats alot of power and multiple decent sized amps will draw alot of power.

Nothing. Just took out the stock one.. This is a winter project.

with a mechman 320, you can get away with what you posted originally. See what your voltage is, then if you need more, just add an additional of a matching series.

edit: biggest one you can fit up front, and then either 3 2400's or 2 3800's and go from there.

My question may have been lost in translation.. Would it be better to use 3x 2400 or 2x3800 and then as a side note (if less is better) maybe I could just use a xs power 7500?

Would I get too much of a voltage drop if I just put one 7500 in the trunk and nothing up front?

yea, it kinda did. I think you will see similar results with either set up [referring to 3800s vs. 2400s], and less is never better when it comes to electrical. i would personally think you would have better results out the the 3 2400s though.
