Got all my pieces cut, 45degree angles cut and port guide (3 1/4") cut as well.
Test fit and it all went together beautifully. It is a very small box (2.5cu) it seems, and I think the Napalm takes up a lot of area (.25 cu ft?). Let's hope it hits low and loud. It just doesn't seem like a 2.5cu ft box would hit low and loud, but we will see.
