Alternator Amps? (Not W/V=A)

[Eggroll]

Anyone have a chart, picture, or website of recommended amps for certain watts (apart from any other car electrical needs). I just want to see what is the max recommended watts is, apparently 220a is the most for my car, even from Singer. (Besides batteries)

Google is your friend .

Yes but 90% of google is people just showing VxA=W, not taking into consideration other electrical needs or box rise, wiring, etc. Google also says that a boss cxx2705 is 5 stars

Just get the biggest alt you can get if you need more add dual alt if you cant get a different car.

none will as all that is dependent on your setup not amp itself.

Only michael replied to me, he has a 220, and iraggi has a 260 on their website, any problems with Dom?

I know bro but its also bad to have a small alt, bunch of big *** batteries, 0 gauge ofc, and put strain on the alt when you have above ~1k+ rms

no really, i did not know that........... ok.

Good guess your car will need 40% factory alts max output. Subtract that from your new alts idle take the rest multiply by voltage then double to account for rise. If factory is 100a your car would use 40a your new alt does 220a max roughly 160a at idle so 120a Times 13.8v 1650w double that 3300w. This is rough but should get you close.

8 x your alt size is what I used to give me some idea of what alt I would need.

Oh awesome man thank you

Watchu mean?

Oh like 8 x amps oh nice nice

like a 270 alt times 8 would be good for 2160 watt amp.. It's a rough estimator bit gives you a general idea of what your looking at.

Ohh **** what can I do with a 220? What if I wanted 3k rms? Do I need 2-3 batteries? XD

I run 2600rms total and I have 1 starter battery, a 2nd battery and a 320 alt.
