according to my calculations i have 3.79 cf left after taking out the port displacement.so at the end i will have around 3.5 cf considering the sub displacement be 0.29 cf.as of power i have 9 amps ranging from 1k- 12k so power is not a problem.
i have a box thats 3.5 cf after displacements tuned to 37hz what fi 15" sub would fit better for this box?
