4 Gauge Dual Inputs/Adapters

[beatzboi 10+ year member]

Im about to pickup a AB PH4000MD, Im noticing it only has 4 guage inputs. I'd like to make sure its pulling everything it can and run 4 gauge to dual 4 gauge input adapters but cant find any? Any one know if they're are even in production. Or would I be better of just doing 4 to dual 0's reducers/adapter

you'll be fine with 4 to 1/0

no need for dual 1/0 for 4 gauge inputs imo

Ok, lemme put it in better perspective. The question I was asking wasnt too precise. My setup (as far as wiring) 0 gauge--distro block (3) 4 gauge terminal outs. RF P400.4, and 4000md are the amps that are currently in. So I want to connect two 4 gauge from distro to 4000md. So would there be any benefit to dual 4s, vs 1 4 gauge? Or should one 2-3 ft run of 4 gauge from distro suffice? This is a 2000 watt amp here so Im just wanting to be sure and safe. I dont really want to have to rerun 0 gauge yet, even though I will be running 2 0's and neg later this summer

just use a 4 awg ofc from the distro for now itll be just fine for that amp. sometimes those distros have 2 1/0 inputs and you can just use the other 1/0 input as a 1/0 output and fuse it to the amp i did that for a while.

With that short of a run from the distrobution block, you're more than fine with one run of 4 gauge OFC

This is Knu's CCA 0 and 4 gauge

CCA isn't great, but even then, I don't think you need more than 4 gauge to that amp.......

I thought RF had trouble with adaptor use

I have several of those amps and straight 4 is hard to get in clean like it is undersized
