@brettmcee,
Use the multiple outputs of your preamp, that’s what they design for. In most cases, vertical biamping gives your the best possible results i.e. using one stereo amp per speaker. If you choose to use two seperate brand amps, external crossover is highly recommended as @cleeds pointed out.
If your amp has XLR inputs, I would recommend using XLR cables.
I am also bi-amping my speakers with a class D amp (ATI-543NC) for bass and a tube amp (ARC VT-80) for mid’s and high’s.
