Short lengths of 4/0 gauge will handle just as much current as a long lenth of 0 gauge. If you ever want to upgrade to a distro block, mount it close to the sub amp to keep the 4gauge distance short and the amp will never know the difference.
Example-
Look at the fuse under your hood look closely at the element, its just tiny compared to the 1gauge but flows all that current.
Why?
Because its very short, if it was longer it would burn out at a lower amperage.
Short lengths of wires can safely carry the same current that long lengths of very large wires can.
