I can see maybe 2 at most ,it creates too many issues the input sensitivity of each amp is different if not the same ,
a amp for the bass for sure a quality SS amp, tom tube or SS
and a Tube preamp , SS amp is widely used or tube .
your speakers will determine this too by their efficiency
thrn if you have to add a external crossover that more added in the circuit which dips never better less sonic purity ,less is always better in 5he signal path . No mention of the speakers being used
and space size needed , if monitors ,then judt get a good powered sub with nice modern app like a Svs ultra 16, or Svs- SB 3000 sub. Then you only need an amp on top .
