power cable adapters or distribution bloc

You have two of the same scenarios; 0g to the block that's 4g out OR 0g to the block then 4g to everything. This is the same thing. Was that a typo?

From 0g to 4g to 0g? It would be pointless. The second 0g (after the 4g) will only be able to carry a maximum of 150amps because that's how much the 4g can carry.

It would be like having 3 water hoses -a 5/8" diameter to a 1/2" back to a 5/8". The second 5/8" (after the 1/2") would only be able to carry as much water as the 1/2" one.

It would just be a waste of money, for the second piece of 0g wire, as it will only allow as much current (amperage) as the 4g.

I would just run 0g to the block with 4g going to each amp. https://www.the12volt.com/info/recwirsz.asp -Check out the first chart. From the d-block you can run 4g no longer than 4feet to the 1200wrms amp and be okay. Since your amps accept 4g, it'll work out perfectly! If you'll need more than 4feet, you should try to find a block with a 2g out for it. The above link to the chart really should answer all your questions.

I'll leave you alone now so maybe someone else will chime in.

Are you talking about using reducers on your 0g to drop the ends of it to 4g in order to allow you to plug them into your amps and distro block? Like this one?
