With the power demands I'll be looking at, I'm contemplating the big 3 upgrade, and came across this site http://dynamicgrounding.com/
on another fo-*cough*-um. The guys have been quite happy with the product, but what do you think. It's mostly just grounding, but 4AWG to both heads with 2AWG from the battery to the frame all for $77. Would this be a good/simple way to do the upgrade, or should I just do it my self with cable from the local Acklands?
What do I really need to upgrade? Do I need to up the grounding from the heads as well, or just the alt - +ve, +ve - fuse box, and -ve to frame?
