Port area for 1.8^3 box

[twomanytoys]

Im building a box for my single Sa 12. The box is 1.8cf. What size Aeroports would I need to tune to around 34 hertz? The sub would face back into the trunk. Does it matter if the ports were ported into the cab or is it better to port it into the trunk? Does it matter where the ports are? This is my first box build so Im still learning.
