So if I wanted to power all the a/v stuff (200x7 amp,pre-pro,cd,dvd,sat boxes ect) in the middle of the room INCLUDING the plasma NOT INCLUDING the subs would a 20amp be enough? I can then do a dedicated 15amp to each of the sub outlets in the left and right corners of the wall OR could those 2 sub outlets share a 20amp?

On a lighter note I found this wall outlet. It is recessed for the power plug behind the plasma. Only thing is it does not attach the flex conduit to it...but as long as its in the wall I think I can grab it to run a few wires through and make it work.
