What size Power wire

[Sky]

Kicker dx400.4 takes 4 gauge.

Soundqubed q1-1200 takes 4 gauge.

I want to run a distributor block. So my question is should I run 2 or 0 gauge in the block.

I always run 1/0 or bigger, the more current you can get to your amplifier(s) the better. With electrical over kill is better, the challenge is finding that happy median between overkill and just plain unnecessary.
