@dadork - I did not have any issues when I set up a couple of different combo HT/2-channel systems years ago. I used an HT receiver and an integrated amp, in combo, just as you are trying to do. However, I was only using one sub, different model sub, and different room, of course.
My only suggestion is to forget completely about the HT side, until you have the subs sounding the way you want for 2-channel listening from your integrated amp. Once everything is good for 2-channel listening, move on the adding the .1LFE for HT, and then run your setup again.
For the 2-channel setup, you only have sub volume, crossover point, phase and location. I'm not an expert on sub placement or setup, so you might want to eliminate some confusion and start a new thread asking how to find the best setup for 2 subs in a 2-channel audio system. Don't mention anything about the added HT portion, as it will likely confuse some/many potential posters and send the thread down a rat-hole.
Again, once you have the 2-channel music system to your liking, you should just be able to run the setup routine on your HT receiver and all should be good.
Good Luck and Happy New Year.
