2 alts or 2 batterys?

Well, right now I have an Alpine mrp f300, Alpine mrp m500, infinity kappa 1, infinity kappa 4. I hope to loose the alpine and replace them with another infinity kappa 1 and kappa 4.

The current draw is well above 200 ampers.

I don't know where to go to have a custom wound alternator. Nor do I think you'd be able to fit 2 in my engine compartment.

If I got 1 or 2 extra batteries. I'm not sure of what kind or ampers.

2 infinity kappa 120.9w. 1 infinity reference 8 inch. Infinity kappa 6x9. Infinity kappa 6x8. Infinity kappa 6.5. Infinity kappa 60.9 comps. With 12 gauge high definition wire at 25 feet each. With 0 gauge nvx wire.

So, basically upgrade the big 3. Then add a yellow top?
