Benchmark amps are known to struggle with some power and current hungry speakers, and running two will actually make that worse, not better, because it halves the impedance seen.
You definitely want to call them and ask, and when you do know the impedance (nominal and minimum) and sensitivity ratings of your speakers.
Suffice it to say there are many speakers that BHK 300’s will power easily that AHB2 will shut down on and be unable to.
Whether yours are one of those, I don’t know. Your trial period would reveal, but call them first to avoid wasting time. They know their amp’s limitations, so much so that each time I’ve called with interest in AHB2 they make sure to ask what speakers I’ll be using
