I just picked up some 8 awg ground wire from KnuKonceptz for this ($0.37 per foot for 8 awg, $0.49 for 4 awg). I am also using Monster 200 series ring terminals with sealed ends to eliminate any corrosion inside the wiring ($3.50 per pair from local electronics store and I bought 8 pairs). I will be using the KnuKonceptz positive battery terminal (which I already had for my amp/sub) and a negative battery terminal from Stinger ($11.50 with shipping bought on ebay). The surprising thing was that the Monster ring terminals were more expensive than all the wiring and the neg. battery terminal combined. It's because they are "Monster" but it was all I could find that were sealed off.
As recommended earlier, I will be soldering the ring terminals onto the wire to eliminate any chance of wires coming loose. Also, every ring terminal to wire connection will be protected further with heat shrink tubing. Basically I'm trying to reproduce 1sty's famous kit (except I opted for 8 awg wire while his was 4 awg).
What do you guys think of me doing another full write-up when I do mine? It's a pretty straight forward thing to do, but supplying info like lengths of each wire and specific contact points might come in handy for the DIY-ers.
