I have two JBL 4311b's hooked up to an old 5.1 channel RCA reciever, but i dont think they get the power they need, what do you guys recomment i get to give the JBL's the real power they need? all i need the reciever to do is take the signle from my computer and power the speakers, no cd player, anything like that, just something with better sounding power output, i dont really want to spend too much on it.
