I would likely take the analog outputs set to stereo mode IF I had 2 identical subs but I do not.
I have an old 8 inch sub and a newer 12 inch sub
So I have the analog output set to mono and take a mono out to a 2 way adapter to feed both subs with the same mono lf signal.
Then I use the gain and crossover on each sub to set to my taste having the basic crossover set at the 2170 at 90hz.
Not sure if it is best way but seems to give good enough results so far.
Still breaking the new speakers in so have not run anew room correction yet and I guess we will see another difference after that.
