How can we mount surround sound speakers on the wall?

Is a surround sound system worth it, and some more questions?

• Well, my main question is if a surround sound system will be worth buying from Best Buy. I have a normal sized room, and I won't be able to mount the speakers on the wall. I can put them around my room, just not on the wall. Also, money doesn't come very easy to me (I'm only 17, can't get a job yet). I don't wanna spend it on something I won't enjoy. So based on those facts, is it worth buying? Also, once I get it, do I just hook my PS3 up to the main panel thing for the system? I don't have a BluRay player except for my PS3, and from what I understand, the TV can't be hooked up to the system. Long question short, can I easily just use the system with the PS3?

• Answer:

  No, not worth the money. They sound "cool", with lots of neat-o sound effects and rumbles and such... but that doesn't necessarily mean it's any more realistic. Whether or not you can use it with your PS3 depends on the jacks available on the back of both units. Get the specific answers on outlets/jacks/connectors for each unit before you buy. There are other, much better things you can spend your hard-won money on.
