Hey I notice Ppl using 2 2/0 for There ground Could you explain to me why so much for the ground and where you would put yours at on your ground because I was planning on using 4 gauge on Body (A) > Head (B) > Coil Pack © > Battery Negative (D) > Body (E) And was going to use 0 gauge for battery negative - body But why would you use so big wire on the ground? I was told the car for the ground needs some sort or resistance for the computer to know, but 2/0 is bigger then 0 gauge. If i decided to do 0 gauge will I be ok you think Here is a site that does my old car grounding its similar to the same identical to my new car for what I am about to do.

Sounds like what you're describing is using large gauge wire directly back from the battery to the distribution block or amplifiers, directly...for a battery to body ground, 0 gauge should be more than enough unless you're competing and every last hundreth of a volt is important

awesome thx for the help was going to use 4 gauge but will use 0 gauge now for better grounding.

form what i know restance is bad in a ground.

i use 2 runs of 2/0 because i didnt wanna have any issues, and while im the type of guy thats never happy i know ill end up getting another saz 3000d... so i wanted to be able to save some work when that new box comes in dig it...
