In the spirit of KISS as others have, here is a simple way to have more control and get as complicated as your OCD allows, add a Mini DSP 2x8 Active Crossover. It makes bi-amping super simple and you can integrate your sub swarm by ear, or get sophisticated and use room correction. The computer interface (connect via USB only while tuning) is clean and intuitive with visual on screen crossovers (start with what the manufacturer recommends) and adjust levels to match your amps.
I had horizontally bi-amped for years with matching amps and it sounded good but recently vertically bi-amped my set up and it has much more punch. So I recommend finding another like model Pass amp to do it and you’ll love it.
I am happy to discuss how to set it up if interested. To illustrate how far you can go: I’ve gone off the deep end with four subs (two in stereo) integrating seamlessly with my vertically bi-amped 20.1 Maggies. There are 12 bi-quad filters in each speaker created by Multi Sub Optimizer from data captured with Room EQ Wizard. The crossovers look crazy and the result is jaw dropping.
