What cables to buy for amp install and how to run them ?

Makes sense. Do it all right the first time and you'll save a lot in the long run

Lemme ask one more question, I decided to run 4awg from battery to distribution block and then 4awg from block to each amp.

Which fuses would I have to pick on this distribution block ? 2 Way Distribution System

And is there a benefit of running Digital distribution block ? it means one more wire to ground the distribution block.

I would run 0/1 Awg int othe Block, then your 4 gauges to the amps. 4 to 4 would work, but 0 to 4 would be better. Digital distribution block will read the volts, some alarm you when voltage is bad, but honestly I would just stick to a regular dist. block. You want to run the fuse that is max current for the wire.
