Hi, i am looking for a surround sound system to hook up in a relatively small room (slightly smaller then 15' x 15') that i can hook up to my ipod. I would use them %100 for music and i listen to rock and alternative. I am looking to spend 500 dollars at a stretch, but that really is a stretch, however, if i there really is a great deal on a moore expensive system, i would consider it. I know i may need an amp, if i do, plz recommend one also. Thx
