Hi, I'm a novice who recently purchased a bose speaker system (5 single cubes, subwoofer) from Sam's Club. I've hooked it up to my Sony receiver, but I have to turn up the volume knob very high on the receiver just to get a normal sound level in the room. The receiver is a Sony rated at 100W per channel, 5 speakers - nothing fancy but used to work grewat with my floor standing Infinity speakers.

Any suggestions on what I should do? The Bose system is the Acoutimass 600.

Thanks in advance.
Mark
