battery terminal/distribution block

Ok, I am replacing my battery terminals and I need to add a distribution block in order to get the appropriate size outputs for my vehicles fuse box. My question is this, I found a distro block that would fill my needs perfectly, but it is a fused distro block. What size mini-anl fuse should I use for the wire to the vehicle fuse box? Vehicle is a 2006 Colorado Crew Cab

The size of the fuse depends on the gauge of the wire. So what gauge are you using?

well, the wire going into the fuse box is a 4 gauge wire, the battery terminal i got has 3 0 gauge outs, one to the alternator for the big three, one to the sound system, and third I was going to run to a DB and have the fuse box wires and remote start wires and any other accessories into it
