If you had a distro block you'd probably still want 1/0 wire going to the amp, since it wants a 150 amp external fuse (you could use 2 gauge, but 4 gauge can only handle 125 amps safely). So you'd have a 150 amp fuse on a wire close to the amp going from the distro to the amp. And if you used any other wires smaller than 1/0 from the distro block to amps they would need separate fuses that are for that specific wire size.You can always use a smaller fuse than maximum for wire size if you want to conform to amp current pull, but never a larger fuse.</blockquote>
