zx2500 amp draw?

[wrathchild281 10+ year member]

I tried to look up past forums on this and had no luck. How much will a zx2500 draw at 2 ohms? Im gonna run 4 for a daily setup and im trying to figure out how many alts and what amperage alts i should run to properly supply these amps with enough amperage. thanks

welll...a totally generic formula is p/v=a 2500/14.4=173 amps*4= 694 amps. again totally generic formula but it'll give you an idea

that on a 14 volt system

i think 2 300amp alts and a few batteries will be ok

So if i have 3 alts that make 300 amps at like 2k rpms does that mean that i will never expierence any voltage drop while doing this?

I mean like if im demoing it or whatever and i have the rmps up while my voltage stay at 14 if im supplying an over exceed ampount of amperes then my total amps can draw?

900 amps would very sufficient for 4 2500's.......some people might say its overkill but if you got the money...go for it. It would be quite the badass setup

If it were to you would you get say 3 300 amp alts or would you get 3 220 amp alts? The first choice would have alot more max amps but only 260amps at idle and the second would have less max amps but 520 amps at idle. Remember this is for a daily only setup.

its a toss up

Sorry if i'm missing something, but 10kW for a DAILY?

That's just insane haha. But yeah, if you can get 3 300amp alt's then go, it'll be plenty for that, if not 3 2xx alts would work out as well
