the standard surround sound is a 6 speaker system, RF, LF, RR, LR, a center speaker and a powered sub woofer. The sub can go anywhere, the other speakers need to "surround" you.
Then you have to find programs that broadcast in true 5.1 sound, my sony give me a pretty blue light when the show has 3/2 sound which is 5.1 surround sound.
I had to run my speaker cables up and through the attic to get to the two rear speakers.
