250a is the LEAST i would go, id try to shoot for a 275a or even a 300a, what kind of car is it? and what engine does it run on.

i'm gonna say no. i was gonna use one 250 amp for one 2500D. is this for comps or daily? that is a lot of wattage for daily.

I would suppose so dude, I know people running 1 2000+w amp on a 80a alt and they are doin great, so it should be no problem man...thats my opinion though, I don't know all the technical crap associated with that, but hopefully it will so you don't have to buy another //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Its a 77-F250 with a built 460 engine.

I'm running 2 Group 35(I think) Yellow Tops uinder the hood. Well if 250 amps won't be big enough 300 should be shouldn't it. I don't really want to run 2 alts

This is gona be my show/comp/daily truck.

I'd get some G31 Yellow Tops as well...

my reasoning is that a single orion 2500D will pull atleast 120-150 amps a piece and then everything else in your car. i never had any thoughts of running 2 of these so i'm clueless lol.

I dont think that a single 250 will do, you have a HUGE power demand from your alone id bet, try and find a 300a.

It'll be fine.

I can get Ohio Gen to make a 300a no problem. I'm just not wanting to run to alts. Just 1. I can run only 1 extra battery besides my main one. IASCA rules.

Then switch them to G31's

Or some Kinetik HC2400's //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
