anyone know how good excessive amperage alternators are? ive been lookinh for a good high output alt for a 01 civic and they have been the cheapest by far for what i was looking for. but im just wondering how reliable they are. second question is my amp says at 15.5 it runs 2500wrms and i have two batteries in my trunk wired up to 16 volts will the new alt help to keep the voltage up there?
