Box help!

[zyliusilver]

Hey all! I need some help configuring my setup. I got a sound stream rubicon 2500 for $150 and a 12" Fi BTL UFO Dual 1 ohm for $100. I am planning on wiring it down to .5ohm (or .7ohm since they are actually 1.4 ohm coils). I am putting this in a sedan. Rear seats do not fold down. There is a ski pass through but I would like to keep that closed. I have an empty 8" hole in the rear deck where the stock sub used to be. I have roughly 3-4 cubes to work with. What kind of sub and port orientation would give me most output in the cabin? I was thinking either band pass (4th order) port through rear deck or sub back port up through deck or sub front through ski and port up through deck. Anyone have any input? Thanks!

I'm curious about this myself.especially 4th ported through factory sub location.I think loudest would be sealing off your trunk with sub and port facing cabin,but then you lose back seats.currently I have a 12 in a ported box in the middle of trunk with sub and port facing tail lights.it's decent but I'm thinking about 4th using factory sub as port into cabin.this is in an acura tl.not sure if it's worth the extra effort or not
