No, I don't know how to do that stuff. I will get it done most likely at Future Shop (like a Best Buy store for you Americans .)

As the size of the speaker goes up, the quality is better?? Or how does that all work? The two in the front are generally smaller right? How do you tell them apart? I mean, do you walk into the store and ask, "Yeah, I need two front speakers and two rear?" ??? Or are ALL the speakers the same, and just the size is different???
