Should I ground from the front battery or just the rear?

[da box king 10+ year member]

Ok so I am running a crossfire vr4000d, a sax 100.4 , and a PPI pc4400.2.

I have 2 pos runs to the back and a 1 neg, all in kicker 1/0. I have 2 deka g31's in the rear an a g34 up front. I am wonderin about my ground tho. I was goin to add another ground in the rear because I don't have enough 1/0 to run one from the front. But will I benifit from running my ground from the front to rear? I have heard some probs when doing so, or should I just do my original plan. Also is it ok to have 2 pos, and only 1 neg from the front, remember too I will be grounding in the rear too so I thought I would be ok, or do I have to to worry about resistance by doin 2 and 1. I'm just trying to decide if I should keep my 1/0 neg run in, or move the ground to the rear? Thanks guys, trying to get some work done tonight.

a common rule of thumb the shorter the ground the better. i would make a new ground in the rear and go to town sanding the paint off and bolting it in wherever you decide to do it.

Usually, you want to run a negative run from your battery upfront to the one in the back. That's how I have my NSB 125, and I haven't encounter any problems whatsoever.

do you think I should take out my ground from the front battery to the rear than? I hear many people having runs tot he front with no probs, or should I just be ok grounding in the rear?

any benifits from running it from the front? and is there a link to find good grounds with a dmm?

yeah its there, but I am in the middle of install and can remove it easily. If I do than I would just use the extra 1/0 for a ground in the rear

i do professional comps and have the fifth loudest car in the world for usaci street beat 1 this year and i have not one ground ran back up front

There is a reason people run them copper is a better conductor than your frame.. Grounding to the frame in the back is just circling back through the frame instead of a through the wire..

that is true but i know alot of people pushing TONS of power and dont run grounds back up front. its a personal preference i guess.

 

[da box king 10+ year member]

I have always grounding in the rear before but I have never ran this much power before so I just want to make sure its done right.

 

[its_a_sleeper 10+ year member]

understandable.... like i said i know tons of people running TONS of power and i know no one that does that but i am sure there are alot that do as well

I think I may take out the front ground, and get a good ground in the rear....prolly near the seat bolts.....any suggestions for a trailblazer ground

If I wanted to go to the frame I would just drill a hole thru the floor and run it too the the frame right? an I would prolly throw some undercoating on the ground too

or would I be ok to just ground to the body, which I always do. The factory grounds are all over the body

So are you debating on having three posi runs and just ground to the frame or what? I dont understand?

If so I would leave it how you have it

 

[da box king 10+ year member]

well I could leave it as a power? sorry for the confusion.

and if I did just ground to the frame, does it have to be direct, or can I just ground to the body which goes to the frame?

I'm just lookin for the best most efficient way to do it, thx
