My receiver is 100x5@6 ohms.

I was wondering if I could add resistor to make a 4ohm speaker 6 ohm. If yes, do you just wire it inline with the positive or negative or both?

You can add a resistor to make the reciever happy and you can choose
either positive or negative.

I doubt it would have a problem driving the 4 ohm load, considering you're going to get impedance swings anyway. Solid state usually isn't too picky :)

I see. I didn't see any resistors with a very high wattage rating, but I am probably looking at the wrong thing.

Reason why I am switching out is I have to turn up the volume to over 1/2 way before the system is audible. The setup I have now are all 8ohms, except the center channel and it doesn't have any problems that I know of.

You should not have any issues with running the receiver at a lower impedance. Just make sure that you watch and make sure that you don't run it too hot. You could add the resistor but just because you can do something doesn't mean you should do it... :fyi:
