I'm doing some work to my engine that's in my Hallett, and I going to order a new alternator. My question is what amp alternator should I be looking at? I have a 454 BBC, 1-wire alternator, with 2 batteries, 4 Kicker 8" speakers and 600 watt 4 channel Fosgate amp, with auxiliary cable that is ran to my iPod. With that being said, should I go with a 80amps or 100amps alternator or bigger?
