I would do 2 runs of 1/0 that then split into 2 4g.

1/0 gauge isn't really adequate. Four 1000-watt RMS amps will draw about 320 amps at 14V, if they are 90% efficient. To be safe, look at the fuses on the amps, and add them up, and size your wire accordingly. Look at the "Wire Guide" sticky at the top of this forum for reference.

2/0 gauge would be much better. A single run, and a 4-way distro block sounds like it would be perfect.

Two runs of 1/0 is the equivalent of 4/0, which is overkill. But if 1/0 is easier to obtain than 2/0, then go for it!
