Sub Not Waking Up

I have a Yamaha CX5100 Receiver and two Sunfire HRS8 subs.  I moved my equipment around in my cabinet, got a new am to power my R/L, and new R/L speakers.  I am still using the same center, rear, and 7.1 channel amp to power the others.  

My problem is my subs will not turn on.  I ran the Yamaha YPAO and sound came from them and it configured them at 2.5.  But after they will not work.  I think they are going in standby and not getting a signal to turn on but for the life of me I cannot figure out why.  

I have another Velodyne sub in another room and it works fine and the Sunfires work fine in the other system.  It is just the sunfires with the Yamaha.

Any suggestions would be appreciated.

Thanks,Mobius

The Yamaha is not triggering them.  When I go through the YPAO process I can hear them kick on and the light comes on.  This does not happen when just listening to them.  I rewired them using the speaker level inputs coming straight from the amp.  This means I cannot use the Yamaha to adjust sub level but at least they work and I can adjust the volume on the back of the sub.  

I have no idea what setting to change in the Yamaha to get it to trigger the subs.
