best way to wire the back batteries and amps

[Lucky 76 5]

I just ordered 2 d3100s for the back of my suv. I have 2 runs of 1/0 running from the front battery (d6500) to the back. I am running 4 sundown 1500s, a sundown 50.4, and a sundown 125.2. What would be the best way to wire all of this?

This is what I had in mind:

Each of the d3100s would get its own run of 1/0 gauge directed from the front battery.

I would run 2 of the 1500s to 1 d3100 and another 2 to the other d3100.

Then I would hook up the 50.4 to 1 d3100 and the 125.2 to the other d3100.

Does this sound like the best possible method?

Or you could just chain the entire battery bank together. Use buss bars and then run all the amplifier positives to the buss bars.

The way the batteries are layed out I cannot run a bus bar as it would be the width of the car. I have to have 1 battery on the left and 1 on the right in order for everything to fit correctly. Would my idea work out alright?

Also is 2 runs of 1/0 enough to run to the back? I only have the d6500 up front.

Run the two runs of 1/0 to the back battery on the left (or right, whichever is closer to the front battery) then run two (I would do 4 to make up for having that distance between the batteries, overkill maybe, but it couldnt hurt) runs of 1/0 to the other battery and connect all amplifier positives to the second battery.

I don't know if I could fit like 25 ring terminals on a single battery lol. Is that the best possible way or is my idea about the same?

I forgot who the dude was but he has an install with one of those Hifonics top of the line amps and he did a buss bar just for the power and ground wires I think you should do something like that. I would just run a couple of wires from the main battery to the one of the backup batteries, then run them in parallel and everything off of one battery. But your way does sound feasible to me, maybe others will chime in with better ideas.
