subwoofer question

[Bass Crazy]

I have a chevy impala and i want to put 4 aq hdc3 12's in the trunk and I wanted to know if anyone knew the difference in sound when all 4 the subs are facing up or facing to the back of the Car or if i was to have a box where i have 2 facing inside the cabin and 2 facing the back of the trunck.

You want the subs facing the same way. Subs up port to the side is what I would do. Dont think you can fit all 4 facing back without choaking off the airflow into the cabin.

[Bass Crazy]

so you're i should have all 4 subs facing up in the trunk?

Yeah, if you wanna fit them you want them all one direction and up is the only real way. Subs up and port back or to the side would be pretty decent IMO.

Yeah subs firing in different directions causes cancellation you want them all to be on the same plane. So for a trunk all of them upward as previously mentioned would be your best bet.
