Is a 270 amp alternator enough?


Recommended Posts

I have a 2003 cavalier and I put in a 270 amp alternator, but will that be enough to run my car and a roughly 5800 watt system? If you need any more info on it please do ask!

What would you recommend? I currently have a kinetic Hc 1200 under the hood and 2 Kinetic hc 2400's in the back. Is that enough or should I get more?

If that were my setup I would get maybe 1-2 more kinetic 2400's but if you feel it might be enough you could always run it with the electrical you currently have and see how much your voltage drops. If it drops below say 13.0 then you might wanna add 1-2 more batts until it doesn't drop as much anymore.

What kind of alt did you get?

this. There is a big difference between an eBay or power bastards alt and dc,singer, or a mechman alt

750??! Yeah, fuck that. Fuck this website, fuck SMD, fuck Steve, fuck all of his butt buddy mods, and their couches.

I would like to learn something here....

How would adding batteries help keep voltage above 13. I assume we are talking 12V bats that usually rest around 12.4 - 12.7 right?
