2 of whatever gauge wire = the 2gauge below it.

 

so 2 runs of 4AWG= 2AWG

so 2 runs 2AWG = 1/0AWG

 

Same thing, but it would be easier to run the bigger wires to a bus bar/Distro to amp.

FYI

 

Edit...

After doing it by strands however it is a significant difference..

 

 

 

2052 strands for 2 runs of 1/0awg

 

and

 

1568 strands for 4 runs of 4awg

 

Thx never thought to add up the strand count.... Lol I feel sorta stupid. If I do like 4k watts should I use like 10 gauge speaker wire? Overkill wouldn't hurt on that would it? It'd be cheap to do like 8 gauge too but I think that's too much maybe......?

i run all 8ga speaker wire not overkill...and im not sure about the cars frame being equovilant to 4ga??

i dont think this is correct because each run of at or knu 1/0 is 5000 strands or so

You WANT full ground runs. A cars frame is equivant to 4awg.

 

Isn't the front battery grounded to the frame tho? So wouldn't it be kinda the same? Sorry not doubting you or anything. Just wondering. Not very good with electrical stuff.. lol

JL did a test on it. Where is all the current getting pulled from? The alternator. The alternator is grounded under the hood. That's why you do the big 3.

Honestly that kind of stuff is basic when running that kind of power. I see burned up equipment in your future

Weird. I always thought the frame would be best cuz its closest to being grounded. Idk in still a newb with electrical this is my first big build. So Im trying to figure this all out now so I don't screw anything up. If I did 2 runs of 1/0 + and1 run of 1/0 - and two - gnds in the back would that be good? Just trying to save some wire but I fess wouldnt save much in the end really if I already was doing 1 run of - to front......

The power supply is the most important part of the build. Should not be skimped on. Power is going to flow over the path of least resistance. How much resistance does a frame have. Welds?

Interesting guess strands dont matter, lol, scratch the editted part above.

 

and refer to the 2 runs of a certain gauge is 2 gauges below the beginning gauge number.

 

Wire gauge is a measurement of how large a wire is, either in diameter or cross sectional area.

 

Edit:

1 last thing lol, catching up on some reading.

 

http://www.thenakedscientists.com/forum/index.php?topic=44574.0

 

Basiclly

With DC, the electrons spread out throughout the entire conductor or conductors so that the current density is the same everywhere. Of course, this only applies if the conductors are all made of the same material.

 

he main reason why you would want to make wires multi-stranded for use at DC (or low frequencies) is to make them flexible.

- One thick conductor is harder to bend around corners, and so is harder to install

I don't. Thats why I'm on here asking questions trying to do it right.

By the way its not the alternator, its the engine block that is the best ground.

The easiest way i see you running this setup would be.

 

adding another battery in the rear.

Running your runs from the front to the rear batt.

From the rear batt to the Amp.

 

The rear batt would act as a distro block and give you more reserve

hes adding 3 batteries to the rear ..where the hell have u been ..the question is it worth making full ground runs from the front battery to the rear battery bank

Lets make this easy. Look at every successful moderate power build. What do you see?

i see ppl regreting adding useless runs to gain .1 in voltage and little to nuthing on the meter

Pulls what in?

The alternator doesn't pull anything in it only generates power. This is not AC, well it generates AC, but thus the diodes in the alternator that convert it to DC.

Also if that was the case why don't Alternator manufacturers have a Neg post coming from the Alt?

 

 

But that is besides the point, even if you are correct the Alternator is still mounted to the block directly, So anything connected to it would still be sufficent

It's called a loop. And they do have a negative. The case
