Randy said that the crossovers are internal to the amps - the signal is

And a word of warning, adding resistors AFTER the amp, the mixing would
work IN THEORY but they'd burn up in about 10 seconds once you actually
put any power through them.

Uh, no they would not.. Let's say the amps are, oh, 100 watts
a piece into 4 ohms. And let's say your sum,ing network has
an effective input impedance of 1 kOhm. That means at clipping,
those poor resistors will have to withstand a mighty torrent of
power totalling 0.4 watts. ! watt resistors would remain cool to
the touch at full power.

This is apart from whether or not such a project makes sense
in other ways.
