Re: Ground Wire question
i've said it before and i'll say it again. 8-gauge wire is OVERKILL EXTREME for supplementing your engine ground system. there is NO reason to use any gauge thicker than 10 gauge. and you don't need OFC high-thread cable either. any cheap 10-gauge will do. this is not a 1000W audio system. no one should be spending more than $20 on cable and terminals. any more than that and you are wasting your money. spend some money on a pofessional crimping tool, solder gun, and some shrink tubing. crimp and solder the terminals and insulate them with shrink tubing. then use dialectric grease when you tighten all your terminals down. that will be better than ANY kit you can buy.
