I was planning on putting in my 270a alt in my 92 accord but it just won't work out in my car. I'm going to have to downgrade now and use a smaller alt. I could get a 180 amp alt or a 230. The price difference is Over 200$. I'm leaning more towards the bigger alt just incase for future upgrades etc but would it just be better to buy the 180 and take the extra 200$ and buy another xp3000? I'm not sure how many batteries I can hook up to a single alt. Any input is greatly appreciated!
