Sub firing direction

[theM_A_N]

I am building two sealed 12" sub enclosures in the rear of a hhr panel van one in each side where the windows would be on a regular hhr. My question is what direction is best to fire them since i am doing an sq build. I have a lot of flexibilty i can fire directly across at each other which i think is best from a purely aesthetic stand point but how will this work sound wise. I can angle to fire back towards rear window or forward but headrests on rear seat will be kind of blocking the sound path or i can angle down to floor or up towards ceiling. I will have plenty of sound deadener so that shouldnt be an issue. If anyone has tried these configurations in a similar type of vehicle your input would be greatly appreciated

IMO ive always liked subs firing up. They look good and sound good Ported or not
