Aww man, RE calc is not all that accurate. You don't know exactly how big the box is? If it's only 6 gross (including port and woofer displacements) that's not very big...

i thought it was a bit off. my last box was 6 ft3 exactly an this box it bigger. i really dont kno but the dimensions i said at the top are spot on. i measured about 3 times b4 an after the glue. even if its not that big its still louder then the 2 15s i had so im on cloud 9. i tested it using a memphis 16-2000D 2k at 2 ohms an i had it at 1.

5 cubes NET is fine for it man. I would have gone around 6.5 cubes but it looks like you had a hard enough time getting it in there.

What year? You need to atleast cut a hole in the rear deck. I had my btl seal off in the trunk and it ripped the sheet metal on trunk lid and 1/4 panel. Now my 96 SS btl box looks like this-
