This may be a little hard to picture, but in some of my apartments I want to install in-wall speakers, connection plates and volume controls. What I want the set up so the tenant can use either connection plate depending upon which side of the room they will place their TV.

I have the connection plates that I believe handles 6.1/6.2, since that looked setup looked like it could be used from either direction to me with three speakers on opposing walls, not counting the sub woofers.

One wall plate and set of wiring would be in use and another would not be in use. If the North wall plate is in use, then the South West side speaker would be the Front left and if the South wall plate was in use then the South West side speaker would be the Right Surround.

If that can be followed, then does this sound reasonable or is there a better way to hook this up. Should I wire from the North wall plate to one volume control to all speakers and then run wire from the South wall plate to a different volume control to all speakers. This would have each speaker getting wires from the two volume controls or should I purchase some type of switch so that wiring comes from the two separate wall plate / volume controls where only one set of wires ultimately goes to each speaker?

I'm not sure if it is OK to have two wires running to a speaker where only is sending a signal or if that would deteriorate the sound by travelling down the unused wire? If that is the case then I could use some type of a switch after the volume controls. If some type of switch makes sense, can you give me a product example I could purchase?
