[QUOTE="thehardknoxlife, post: 1497197, member: 563104"] I was wondering what I would need for running a 2nd alternator. Now before I get 50 post telling me I am an idiot it will cost more than buying a HO alt, I will say this. I have a sr20de engine. It comes in rwd and fwd nissan cars. The fwd has the alt on the left of the crank and the rwd has the alt on the right side of the crank. I can take the rwd alt and brackets(which I already have) and mount the 2nd alt on my fwd no modifications except a belt. I would need something to regulate the voltage any opinions on what to get? If the one alt is running just the stereo and is pushing 3000 watts I would think the stock 110A isnt enough? So my next question is how many amps does 3000 watts pull from the alt. I can have it wound to be 160A or so. I can do this for less than $200 on my car v/s the price of a 220A $450 is the cheapest I could find. That was quoted on the group buy. [/QUOTE]
