If you want to go a little easier on your alt get a T1000.1 They're way underrated and solid amps. The birth sheet on my old one said 1,380 @ 2 and over 1500 @ 1. Liked it so much I just bought another one from a pawn shop. And it was pretty efficient. I ran it on a 4 gauge amp kit and stock electrical and didn't get bad voltage drops at all.
