Why don't you have the big 3 upgrade yet? That's a big SUV...my Tahoe had 2 gauge wiring for the big 3 and I'm willing to bet yours will to. 4 gauge wire is a downgrade from it. Also why are you using 2 batteries when your running less than 1k? A stock electrical, and typically bigger SUV's have around a 140 amp alt, will have a beefy electrical but I myself would still upgrade the 3 charging wires. Also a stock electrical with big 3 done and nothing else will handle 1k-1.5k.</p></blockquote><p></p>
