Hello. New here. I have an Onkyo AVR606 and I have to sets of speakers just to play music on my patio and by the pool area. I just bought some new Bose speakers and they sound "tinny". Not enough base. So I cannot figure out how to adjust sound on this AV receiver. No matter what I do nothing changes. Switching to different listening presets, etc. Maybe I'm not saving the setting correctly, I dont know. But I have a suspicion that the receiver is not putting out full power. It is a 7.1 surround unit but I'm not really using it for that anymore. Can anyone tell if maybe the unit is set to project sound to 7 speakers and not four thus less power. I'm just a novice but have always had a receiver. Again I cannot get any sound profiles to select. Its just too much treble and I know the bose can play some bass. The only other thing is it goes thru a speaker selection box. I don't know if that matters for sound qualtiy. Thanks.
