Why?

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Make sure each sub is in it's own enclosure, wire 1 up to channel 1, one up to channel 2 and the 3rd to the bridged outputs of channel 3 and 4. Thus the reason for the separate boxes. One sub will get more power than the others but if the gains and crossover points are set correct all should be fine.

you could also set it up in "3-channel" mode if the amp is capable of it.
