Does the impedance have to match?


I have a cheap all in one receiver/dvd. I want to upgrade the speakers that came with it. All the speakers that came with it are 3 ohms including the passive sub.
My question is do I have to change all the speakers to have the same impedance including the sub. Or could I just change the front and center speakers. It is connected to the tv in the livingroom. I only use it for watching football and movies. I have a 2ch set up in another room for music. My girlfriend likes the way it looks in the living room, so the receiver has to stay. I just want it to sound a little better without blowing it up.

Yes it is a surround reciever. So you guys are saying that I could run say 8 ohm speakers for the fronts and center. Then it would be ok to leave the rears and sub with the 3 ohm speakers that came with it? I was under the impression that I would have to change them to 8 ohm speakers also. Thanks for your input.
Good point Unsound, but this receiver is staying put for the time being. My girlfriend liked it and bought it. I put all of my money into the 2 ch system that I have listed this site. I just can't stand the sound of the crappy speakers that came with the receiver much longer. My girlfriend has agreed to let me change the speakers, but likes the all in one receiver/dvd player unit. I'm sure with some better speakers it will at least sound more tolerable. Down the road i hope to talk her into a better set up, but for now i'll have to work with this. Thanks for your suggestions.
