Finished my upgrade, wound up using double strands of 4 gauge (I have like, 100 feet of it sitting around) for:
Alternator to Batt +
Alternator to Chassis (bolted right to the casing)
Battery - to Chassis
And for the hell of it upgraded the fusebox wire to a single strand of 4 gauge.
My subs hit a LOT louder, and now my headlights dim at 25-27 instead of 20 (out of 30 on my HU).
Now I just need to find a HO alternator somewhere for when I add two more amps, and **** is it hard...
Edit: Or if anyone has a better alternative I'd love to hear it, because I've read that HO alternators can die a bit quicker, and I plan on driving my GP for at least another 4-6 years.

^I did find this if anyone thinks this company is reputable, I e-mailed them asking about a warranty.
