i have a current 2.1 speakers subwoofer from philips and it only works for my pc mainly but ipods work and my ipad but it is not really strong enough however i edited my songs and adjusted the bass it only adds a bit of booming to my bed because i can feel it but i want something for ps3 and i was looking at this one from walmart:http://www.walmart.ca/en/ip/surround-sound-speakers-z506/6000049277495
and i have this one atm:http://www.walmart.ca/en/ip/11735180-philips-multimedia-speakers-21/6000137252013
is it worth buying the 5.1? And if i need the cord for the surround sound system to hook up to ps3 where do i buy it at walmart?
