First question, by the 'original bass column' do you mean the original Genesis G1 ( pre 2016 ) VS the current Prime ?
Prime | Genesis Advanced Technologies | United States
G1 = sealed four 12" front and four 12" rear .
Prime = sealed six 12" front and six 12" rear .
Second question, The Genesis G1 main panels are dipole (ish) but are the bass column's dipole or monopole ?
I'm assuming monopole because they are sealed , and an isobaric dipole ??? would simply be a waste of useful cone area.
Monopole = pretend all of your drivers are facing forward, ie. front and rear drivers both push out simultaneously.
So, it looks like you are building Two stack's of four Rythmik G22's
Rythmik Audio • Dual opposed 12" servo subwoofer G22
Now that's a much simpler question. How do I wire a single HX800 amp to dual SW-12-04 sealed subwoofers?
OB H/W Frame Wiring Info / Diagrams
HX800 expanded
The dual amp HX800 has eight connection wires, divided into two separate groups, amp #1 & #2 ,
Each amp has 2X main voice coil outputs AND 2x servo feedback inputs .
Thick Black amp #1 : +++ voice coil #1
Thick Yellow amp #1 : ---- voice coil #1
Thin Red amp #1 : ++ servo feedback #1
Thin Black amp #1 : - -servo feedback #1
Thick Black amp#2 : +++ voice coil #2
Thick Yellow amp #2 : ---- voice coil #2
Thin Red amp#2 : ++ servo feedback #2
Thin Black amp#2 : --- servo feedback #2
Pretty straight forward ONCE you clue into the oddball color flip between voice and servo connections .
Hobbs and HAL am I missing anything ?
