I'm def not an expert but I found these. Both of these are must reads for you. I bet most of your questions are answered in these two threads. Lots of really good info. I would think that once you have the big 3 squared away you need to run 0g from the battery with an inline fuse big enough for both amps to a distro block and then 4g to each amp at least that is how I would do it from what I have read. Anything other way and I think you will have one or more choke points for the power and have problems. Just my 2 cents...

Good luck bro.

Fusing properly doesn't hinder current. And fyi, you fuse for the protection of the wire, not for the equipment or the power being ran. You fuse so that the fuse blows, before the wire starts a fire, in the occurrence of a short somewhere. So if you get OFC 0 gauge, you fuse for 300a; if you get CCA 0 gauge you fuse for 250a; if you get OFC 4 gauge, you fuse for 150a.

So much this. Fusing is for the wire, that's why you use a fuse rated for the capacity of the wire. It's not for the equipment.

Thanks gckless!

See this thread even helped me! I had no idea to fuse for the wire and not the equipment. It makes perfect sense tho... Wish Knukonceptz would have told me that... I'm running 0g from batteries to distro block with an inline fuse and then 4g to two amps and they told me to add up the total of the fuses in both amps and go over by 15% and fuse for that.

So if I'm reading this right I should run a 300amp fuse since I'm using OFC 0g from the batteries then?

Sorry not trying to hyjack the thread.

okay, thanks. that makes more sense

understood now. could you run 4 gauge ofc between batteries, or you want 0 for sure?

not hijacking at all, I'm wondering some of the same stuff. lol

That's a question for someone else. I don't know anything about the kinetik batteries. I have only run optima. Currently, I am running ~1700wrms on my factory alt with no front battery and one g31 blue top in the trunk. It does dim a little at idle though.


I'm running 350a on my 1/0 //content.invisioncic.com/y282845/emoticons/sneaky.gif.7189749b3a3f769e8815b47e8ae87f88.gif 150a on the 4ga

that good or bad?

They are not wrong. You can always fuse lower, just never higher. Also, you need to fuse every time you switch wire size/capacity. So, in your case I would suggest a 300A on the 1/0ga, and then 150A at the most on each of the 4ga wires. Personally I fuse for the wire (largest capacity the wire can carry) for the main run and then for the equipment (what Knu told you) after the distro block.

You will want 1/0ga between batteries almost always.

okay. And for fusing lower, if i had a 120A draw on an 80A fuse, is that fine?

Thanks that makes sense. I was only going to run the one fuse in the 0g. I will make sure to get two more for the 4g.

Since this thread seems to be getting some really good advice anyone care to take a look at this thread in Wiring, Electrical and, Installation help called ***** See what you think? *****

I can't seem to get anyones opinions.

what's the thread called?

It is called ***** see what you think? *****

I will warn ya it is long tho lol.... I should have made it shorter and divided everything up and put them in their respective sections.

sir, you may have to spell out the thread. It keeps blocking it.
