What size alt should I be looking for?

[Davecubs14 10+ year member]

Been looking for a new alternator now but not 100% how big I really need.

I have an aq 2200d right now but looking to get another one or the 3500d in the future. I have an xs power 5100 up front, 3100 in back. 2 runs of 0 gauge to the back. 1 pos and 1 neg. Big 3.

I was thinking of either mechman or dc. But mechman only offers one for my car unless they build one. It does 165 at idle. Do I need more than that?

I would call up DC, I want to say they can get you some alts from the 220-280 range, and they actually rate on idle power.

I rate my power at 700rpm for this vehicle, it can idle higher or lower, but that is what it puts out at 700rpm of engine speed.
