4/0 cable

Does anyone know if anyone makes grommets for 4/0? I plan on doing a do-over of my power runs

Windy Nation. Buy all my lugs in bulk from them.

Thank you. I have some lugs atm. The grommets is what was stopping me from going in for a rewire

IDK why I read lugs.

It's cool. Could be muscle memory. If you or anyone has recommendations I'm all ears

Harbor freight? I'm bound to end up buying electrical tape and zip ties lol. I'll see if they have it in stock near me

Speaking on power runs... How many would you recommend? From front to back. For about 10k RMS?

Google says 4/0 can carry 310 amps. Although, I don't trust those numbers. IIRC, 1/0 oversized car audio OFC wire is rated for 300A. So, I'd say reasonably, it should be good for 500-600ish amps.

10k watts, let's say 70% efficiency. 10,000/.7= ~14,280A draw on electrical system. 500A safe bet per run, and you should be good with 3 runs. Although, if you know the current rating from the manufacturer, I could do some better math.

I ran 4 runs of Sky High 2/0 OFC when I had quad alts, 32 batteries, and four Vital Power 7k's @.5 nominal. My voltage drop was minimal. That being said, You would probably be ok with 2 runs. I definitely recommend dedicated ground runs as well. That's a lot of current to run through the vehicle body.

I ran 2 power and 2 ground runs of 2/0 welding cable with 10k rms. Alternator size is the biggest determination IMO.

Yeah, I think 2 runs would be plenty, regardless of what google says.

Looking at knukonceptz they claim over 600A @ 20 ft. I was gonna double that to stay safe. I don't crank it all the time but for when I would like to know I have a good flow of electrons

I have a singer 320. It's doing well with what I have now. My system consists of a crescendo 2000.4 and a taramps bass 8k.

What amp(s) are you running?

Sorry just posted it. Taramps bass 8k and a crescendo 2000.4
