What mode are you using when listening to music?

The front speakers sound great through the carver but I can barely hear the rear speakers and the center speaker when I have them all on when listening to music.
I can't hear my center and surrounds either, but I listen to them in the two channel stereo mode. ...and I like it that way. IMNSHO, two channel recordings sound best played back in two channels but YMMV.
Try one of the DPS modes, DPL, or even 5 channel stereo if it's available.
