Big 3, over sized guage?

[Vtechno]

im planning on upgrading the "big 3" in both of my cars. 4 guage is recommended and cheaper that 0, but i have a nice bit of 0 gauge laying around, that i have no clue where it came from.

is complete over kill or would it even matter? use it since its free or just sell it and put the money towards buy some new 4 gauge?

If you've got the lugs to fit the 0, use it. If not, sell it and get the 4 and some lugs.

i used 4 gauge for my trans ground and starter, 8g for my fusebox and i think its 12-16 for the rest. ive had 0 issues to begin with and no issues to this day.
i did it to my 3g lude too esp cause i ran a 5th gen accord alternator rated +20 amps than the oem. great improvement when u turn on the a/c hehe

by lugs you mean connectors? and thats the point i just have wire. ill need too buy some.

would there be any difference in performance using 0 than 4? if so would it even be noticable? as of now its just a stock civic with a 1.6 BUT my h22 is ready to go in (just waiting on time too do it) and i have half the components for my 6-700watt system.

guess i should ahve mentioned that before.

what is the big three? ford,gm,chrysler? if your going to make a thread like this be more specific so that if there is indeed any relevent information it would allow it to be more easily searched.

I'd just use 4 gauge. That's what I did when I did my battery relocate. All the power and grounds in my car are 4 gauge. I personally think 0 gauge is a bit of an overkill, unless you've got a huge system in your car.

Put would it be a bad thing to use 2 or 0 gauge ???

Its not going to hurt anything, its just unnecessary. I did it with 4 gauge (except for the the battery to tranny, thats OEM) and I thought THAT was a bit of overkill. lol.

Just make sure that you leave enough slack for some engine movement... especially if your motor mounts are as garbage as mine.

Ok nice i might be doing this after i install my brakes/bearings and header .

Use the 0 gauge cause it's free.

[brsteinbach]

Do you have a "big" system in your car? 500rms or more. If so use the 1/0. If you don't have a system then use it anyways. Like Sonik said it's free, Why the fuk wouldn't you use it lol.

"the big 3" is a common upgrade to your vehicles main power wiring.
op: The difference between 4 and 0 gauge will likely be unnoticeable. I would do as visualpoet suggested just because 4 might be easier to work with.

common upgrade to what power wiring?

[sonikaccord]

common upgrade to what power wiring?

Batt neg to chassis
Engine block to chassis
Alternator to Batt pos.

Used to decrease resistance in the cars charging system.

Yeah, 4 gauge is way easier to use, and go price out some 0 gauge terminals, they're not going to be cheap. I think I paid a dollar a piece for my copper 4 gauge terminals.
