I agree, you can have 1000 amp or a million amp alt and it makes no difference unless you draw that.

however, what I mean was, over kill in the sense of buying a 200 dollar power master alt for the 120 amp square back.
when you could spend 60 bucks for the 78 amp parts store one and be doing just as well.

there is no reason to spend big money on a big amp alt if you don't need the amperage.
