Search "ported" and "vented" as topics in this forum. You'll have plenty of info.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

OMG! You'll need a tractor trailer for that box. And how are you going to construct a port that is a negative length?

Post the actual model number of your subs.

nightrider, here is a breakdown and i hope this helps. a square foot is 12" by 12" by 12" box. Now immagine that 154 times. thats friggin huge. most sedan trunks are only around 13 ft^3 at the most. you would need a semi trailer to get 154ft^3
