Is there a science to the way a subwoofer box should be facing in the car's trunk, or is it dependent on a vehicle itself? In other words, in most systems I see, the subwoofer box is firing "backwards", where you can see the subs head on when you open the trunk....I have the subs firing the same way in my 99 Accord, both Rockford Punch XLC's in the sealed box firing backwards, towards the outer area of the trunk....would I get harder hitting bass if the subs fired directly through the seats? I was told in a sealed trunk such as mine, the bass should fire backwards like it is, so the "bass wave" has "room to develop"....does this make any sense?

What about vehicles like SUVs or hatchbacks? I was told vehicles like these can have the subwoofer boxes firing forwards towards the passenger cabin because the back portion of the cargo area of these vehicles are all open; the bass can pretty much fire right up and over into the passenger area....any truth to this? Should I turn my box around in my trunk to fire through the seats themselves?
