Invert mounted sub - polarity/phase question

probably an easy question for those who know - if i have 2 subs mounted in a common chamber box and one of the subs is invert mounted does it need to be hooked up out of phase with the sub that is not invert mounted?

here is a ghetto drawin of the box

does the sub on the side needs to be hooked up backwards/out of phase with the other one?

In a setup with two normal mounted subs, they both move in unison so logic says you should reverse the polarity with 1 sub inverted or else you will have the subs fighting each other.

Yes, you have to inverse the polarity of one sub.
