Would there be any sound difference with sub back port back vs. sub up port back. Its going in the back of and suv.

Ok I drew up some models one is sub and port back and one is sub up and port back. Do I need to change the port on the box with the sub facing up or is it ok the way it is.

Thanks in advance for the help. Alright I am planning on getting a 12" Fi Q D2 and already ordered a sundown SAZ-1000D to power it. I've never built a box before and I dont trust the audio shop here. I want to build a L shaped ported box. Its going in a 1997 chevy blazer so I have room. First should I go sub up port back or sub back port back? What are the benefits of each keep in mind I'm not going for spl. According to Fi "Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume." So I want to stay as close to that as I can 3/4" MDF board is what I will use. I downloaded a box calculator from I think Basshead (thank you btw) and I punched this in Any tips revisions anything at all will be appreciated also do you guys think I need to brace it or not. Thanks again.
