Down firing in a situation that will already be space-confining is usually a bad idea. The subs will need room to ventilate into the listening space. Unfortunately, up-firing into the seats will also tend to muffle the sound and alter perceived frequency response. It is for these reasons I personally dislike 'under seat' mounting setups in most situations, there is virtually no ideal.
