How do i wire 3 amps in my car?

Easiest way would be to run a 2 or 4 gauge primary wire to a distribution block then use 6 or 8 gauge wire from the distribution block to the amps. I had a similar setup but it was 3 1000watt amps and used a 0 gauge wire for my primary and 4 gauge wire for my amps the distribution block should use 80 or 100 amp fuses.
