I often have to wire speakers that are two 8 ohm on one channel and two 4 ohm on another... It always seems like when I put the two 4 ohm speaker together in series that the polarity gets flipped. I end up putting the negative to the positive of the amp because it sounds better... Is there some sort of rule to use when wiring this kind of setup so that it comes out the same polarity as the other speakers.
Also sometimes i have to wire tweeter to these same channels... is there a specific leads to use to get the positive and negative correct?
thanks,

If you wire them the same, the polarity comes out the same, no question about it. Has nothing to do with the polarity.
What may be an issue that if you use 8 ohms on one channel and 4 ohms (even 2 x 4 ohms in series to get 8 ohms) there will be differences in directivity, possible efficiency, and freq response on the listening position.
Possibly that causes the differences you hear.

I agree can be very much problems with impedance and phase (I thought the same).
Going back to OP post.
That's not good. Build a system that is the same on both sides for a good stereo.
Now looking at what you said:
two 8 ohm on one channel:
if series = 16 Ohm
if parallel = 4 Ohm
two 4 ohm on another:
if series = 8 Ohm
if parallel = 2 Ohm
tnptruck,
How is it that you have the same impedance then, impedance does not match?! Better redoing your system and thinking it again... 😉
