I have a civic that has a 75 amp alt stock. I am going to be installing 2 amps that will have that will produce roughly 1500 watts (JL 1000/1 and JL 450/4). My stock alt will not be able to make the power that I am needing. I can not decide about the size of alt that I should upgrade to. Originally I was going to get a 150 amp alt. Then using the logic that bigger is always better....I considered a 200 amp alt.
Is 200 amps overkill? Any negative effects on the electrical system by giving it that much more power?
