I'm looking to purchase a receiver to run the sound and video in my bar/living room. The room is 16' wide and about 40'-45' long. I'm going to be using ceiling speakers (not yet purchased). I also want to mount 2 outdoor speakers outside. I'm thinking I can get 4 speakers inside and then the two outside. I really have no idea what kind of receiver I need or whereto place the speakers (or even what speakers to buy). It's mostly going to be st up for music and sports. Do I really need it to be surround? I can't see how this would work because of the layout of the room. I kind of want all the same sound to come out of all of the speakers. Also is there a way to have the 4 speakers inside on while the 2 outside are off? I know I'm missing things I want to ask, but that's good for now.
