ported box for 3 lvl 4 10s

[FroznBeavrBALLs]

I just wanted to see what yall think. I am not the best at designing boxes but This is one I did today for my next build. Its going in a trunk...

3 cubes after displacement

Displacement:

.45 for the subs

.2 bracing/45s (not shown in pic but they are accounted for)

.76 for the port

Port:

Tuned to 32hz

14 square inches per cube.

Total box volume is 4.41 cubes

The port is my main concern... Is it ok the way it bends, and the opening inside the box??
