1 Fi Bl 15, or 2 SA 10s?

[Bryan Mckendry 0]

I was wondering what would sound louder?.  One Fi bl 15 tuned to 32 hz in a 3.1 cu box firing upwards in the back of a trunk. Or 2 SA 10's in walled off trunk?

And if i was to go with the 2 10's, would it be better to seal off the trunk and have the subs firing towards the front of the car, or would it be louder to wall off the trunk having a port and the subs facing the front of the car?
