Hello, I'm trying to setup my new speakers and receiver and had a question in reference to the volume control. I have an Onkyo SR605 and Polk RM6880 speakers. Now to start I dont have all the speakers set up just the center and front left and right along with the sub. After reading multiple posts here I went the route of wiring the speakers directly to the receiver and using the white L to the sub out on the receiver. Like I said I havent gone any further than that but something is bugging me thus far. In order to get decent sound from then speakers I have to turn the volume up on the receiver to 55+. The sub isn't as loud as I expected from the look of it but it's alright. My question is, is this normal? The volume goes to 100 so I have room to climb, and as I said Im not done calibrating, etc., but this is something that I just wanted to ask at this point.
