I have a 2006 bmw 550 with a 9" by 14" pass though in the rear seats. Is it better to mount a subwoofer directly behind this opening firing directly into the car cabin, or have a sub in the trunk firing toward the rear or side of the trunk

For maximum output and frequency response your best best is firing straight into the car.

Wouldn't an enclosure with 2 subs in a "V" shaped opening fired thought the pass-though work as well? Up 3db?

Hey, you have the same thread posted twice. You need to close one out so all responses go to the same place.

it really depends on the person and the car. in my experience pointing the subs in the cabin or away from the cabin gives the most output. i have too much bass so i have my subs firing up into the rear tray where i removed the speakers. this allows me to get some of the sound of the subs in the cabin without taking all the output.

even supposing so 3db from an additional sub is an expensive way to get 3db. you could deaden the car or redo the box for 3db.

in my experience facing the trunk is no different than facing the seats. try taking out the rear speakers if you have any. that should get some air back to the trunk.

on my cobalt firing them forward was always a bad move, with them going backwards they rock.

there has been a lot of coverage on this matter as for firing forward or backwards....

firing backwards will give more cabin gain and cut out cone noise,,, but it also reduces bandwidth, and for every thing that rattles in your trunk you lose a little sound,,, and this way you also lose output outside the car if that is of concern to you,, because of noise cancellation...

firing forward you decrease the punch that the system has,, but your frequency range is much smoother,, and the sound outside the car is more pronounced,, also you eradicate much of the trunk rattle this way too...

if you are wanting to put them forward and fire them through a ski hole.. then pull the seat,, and cut the entire metal sheet out.. put in the box and put your seat back on.. I did this on my mercedes...

because if you fire them forward the sound is only coming through the skihole... a lot of the sound gets reflected back into the trunk and can cause timing and cancellation probems...

If you cut out the entire sheet behind the seats you have less reverberation,, and it sounds much better.....

i noticed a great increase in sound inside and outside the car with this method...
