We need more info. Same amps? Different? Which ones? I would go to Integrated "A" with all sources then line out (fixed tape out not variable preout) to Integrated "B".
Integrated A = the one with a better sounding preamp section if A/B are different
If the power levels are different on the amps the higher one to the woofers of course.
Good luck!
