I'm currently looking to finish my downstairs theater room w/ a surround sound that fits the screen. I have a 120" projection screen downstairs, I am going to be hooking up a 80" tv behind it (to just watch regular tv shows). I'm wanting to get a 7 channel surround sound system to hook up w/ it. So i would need to find a system able to output to 2 devices (I will not be playing bothing the tv and the projector at the same time). I also want to hook up 3 speakers outside. These 3 speakers will not be used for tv sound will be used strictly for radio and ipod during entertainment. Do I need to get a separate system for this, or would it just be easier to do a separate system for this? What recommendations do you have? My room is about 15" wide, by 25" long. We sit towards the back wall of the room. Also for the 3 other speakers I would have 1 under a deck, 1 in my rock garden, and 1 in my garage (so this one doesn't need to be an outdoor speaker). I would prefer these 3 be wireless as I'm not so much worried about quality, it'll be background noise. I'm hoping to keep my budget around 800 or less (preferably less). is this doable?
