How to determine what size alt?


Recommended Posts

You all are off. It takes 100 amps at 12 volts to make 1200 watts. Amps x volts = watts. And figure on 80% efficiency, so realistically 100 amps at 12 volts makes 960 watts.

I prefer to err on the more than I need side.

My system is going to be around 1100 rms and im planing to have around 200(potential) amps at idle a d3400 underhood and a small batt in the back to support that.

Just get the 370 elite and you'll be golden for a few future upgrades when you decide you want more power ;)

Bigger isn't always better when it comes to Alts.

I'd rather have a smaller alt that does more at idle than a bigger alt that does less at idle but more at 2k Rpms.
