How do you run a bad beat jackpot in a home game?

I've decided to make it any full house beat by a full house or better. Both players have to use both hole cards. I wonder if someone hits quads if their kicker counts as both cards. Ex. player is holding AJ and the board is JJJQK. Does that count or should he be holding JJ w/ JJQKA on the board?
I wonder which way I should go?
Thanks.
