One time shot

[KARLEON 10+ year member]

Im in the process of designing a new box for my honda accord. Its going to take up my WHOLE trunk. Im going to try and get 8 cubes out of it. Anywayz, my original idea was to make the box and have my subs facing up toward my back dash instead of the traditional style of facing the trunk.

Now i've searched and searched and i hear that facing the rear would be the best. But the way i had on building my box, it would be hard to put the subs into the box while using the max area of my trunk for that extra airspace.

So i guess my question is for all the people who have been into caraudio for years and have done their fair share of installs, how much difference in ouput can you tell if you face the drivers up or towards the rear? Is there some general rule to go by, like leave a minimum/maximum of 3 or so inches from the rear dash or rear of the trunk for sound waves to flow. I have no clue, but since imma have to build the box inside my car, i want to do this one time and one time only. And i really cant play around with different boxes because of how big this box is going to be. So input would be greatly appreciated.

Oh and i forgot to mention about firing the subs into the cabin because i do have fold down seats. Would that be better than facing them up and to the rear, or does the rear wins hands down.

If you want to fire them and the port into the cabin, just seal it completely off from the trunk.

And how would that sound compared to firing up and rearward?

Face them to the rear. My 12s were louder than it was firing towards the back hatch than it was facing the front. Trust me i went from a 133.7 dB to a 135.4 dB by turning the box back to face the rear hatch.

Did you properly seal them off from the cabin while facing the in the front? If so, that could have been your problem. So far, the people i have talked to through IM said the cabin should be the best if sealed off tight and they said the rear should be pretty good too
