do the big 3, along with a back batt(kinetik 1400/1800,batcap 2000, powermaster series,etc)

never change the wire, but add on to it. Yes all 1/0 is best, or even bigger.

invest in a voltage meter to keep an eye and see what you drop to.

if you dip below 12s then you definitely need an alt.

Ridn hit it pretty well on the head, but change out your stock battery, and drop the cap. The reason I say drop the cap, is beacuse its like a band aid on something that needs stitches.

If you need further help please ask.
