sub and port placement

[Lschevelle 10+ year member]

Im starting my build in about a week or so and i narrowed my design down to two options. The first option is to have the sub up firing at the rear deck with a kerfed port(s) firing back or sub up firing at the trunk lid with a kerfed port(s) firing into the cabin. after doing a lot of searching i see a lot that like the sub up port back. The reason i chose these two designs is because i cant do both sub and port back or sub back and port to the side. Which option would yield better results? I also its vehicle dependent but my box will have to be build inside the trunk so moving it around is pretty much out the question

subs up equal crazy rattle that will eventually lead to broken trunk lid.

I liked your sub back and port up design...could also do subs up and port to the side as well

with the sub up and port back the subs will be right under the rear deck. i was going to put deaden the trunk lid if i go that route anyway only reason i changed from the sub back port up design is because i read that when bending aeros it cause port noise and two 8" would be best but its hard to find them and the three 6" wouldnt have enough port area
