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.
This is what I use.

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.
What amp(s) are you running?
