Two speaker pairs to a single amplifier.

- + - + = 8 ohm load (12)

- + = 2 ohm load

in series = 8 ohm (12) YES
p

--------
2 ohm NO

8 to 12 ohms in series YES
1.5 to 3 ohms in parallel NO

Keep the runs (cables) as short as you can. Will it work? Yes. How well will it work? Don’t know.
May start a hole ne trend! :-)

Just in case it's not clear. If wiring in parallel (which you don't want to do because it will present a troublesome 2-3ohm load to your amplifier), you would simply connect both sets of speaker wires to the amp's binding posts.  To wire in series (presenting a more benign 8-12ohm load), connect the positive wire of speaker A to the amp's positive binding post. Connect the negative wire of speaker B to the amp's negative binding post. And the connect the two "left over" wires together. I use wago lever clips for this purpose. Standard electrical wire nuts is another option, as is "mash together and wrap in electrician's tape".
