Mcintosh MA-7900 home theater bypass with subs - not doable?


I acquired the MA-7900 and would like to use it in HT bypass mode.  I have my front mains and two subs (via Pre Outs) hooked up to the Mcintosh.  I want the front speakers AND subs to work on HT bypass, but can only get the front mains to work.  The subs will not play in "Passthru" mode.  

Does anyone know a work around to this or is this just a product of the amps age?  My Anthem has HT bypass for subs and mains.

I think the preamp outputs will work. Have you thought about high level inputs to the subs and bypass EQ when listening in stereo?
