I have a 2000 Chevy Blazer(s10) I was wonderin if anyone could tell me what size alt. I need I will be runnin around 2400rms

thankx for any help

the bigger the better. why? cause you'll know you have a stable ass electrical plus, if you ever decide to add more more and subs or such you know you'll have the electrical for it.

Bigger isn't always better and unless you want to spend some money, it's not worth upgrading. Don't get anything unless you need it. Try it first, if you need to upgrade your electrical system, you'll know.

And looking at your sig, it seems you've already decided.

well i got an option of 200,250, or 300

my lights dim now but i havent done the big 3 yet either so thats why im askin i am totally new to HO alts. and multiple batts, so i have no clue how to figure what i need...so would the 300 be overkill, i probably wont ever go bigger so what do u guys think i could get away with.

i want to be able to bump at idle

thankx

i wont ever go bigger than my new system is what i meant i am gettin it

300a seems a bit excessive for 2400w.

do u think i could be alright with the 200 or should i get the 250, i will have a yellowtop under the hood and maybe 1 or 2 in the back

I would say the 200a would be fine with one stout battery under the hood for that little power. And even that is still overkill.

Even if you had an amplifier that was 100% efficient (which no one does), you would have to be hitting that full 2400w @ 12v to pull a full 200a. I'd guess you'll only realistically need 180a at the most.

thank u for the help, ill go with 200 and a yelloetop.

your lights dimming is normal, just get a farad cap and it will ease the flow of current and no more lights will dim

Ummm.......ya........ No.

Don't make me ban you.

no caps, HO alts/batterys for me the only thing close to a cap I would even think about runnin is a BATCAP

A cap will only properly work with a low enough ESR (and last time I checked there were on a few on the market), and to filter/stabilize the voltage. Help me out he John, I can't find the wording in my head right now.

In other words, a cap is pretty much useless if not for a proper electrical system. They're marketed as a band-aid for poor electrical systems, but it's nothing more than a support system to an already healthy one.

I'm pretty sure ESR only really applies if a bunch of caps are used in a set. Like in an amp.

Either way, the fact of the matter is it doesn't hold a large enough charge long enough to help for more than a second when you system needs the power.
