You need to provide the exact model of the driver and if you want to calculate yourself then get Torres calculator.

I saw the replay of others they ask which song you will listen and play ,I listen the songs which were more bass boosted and to shake the car and glasses and should listen more  out side the car and can you send me the songs list and songs in google drive

You will need to find manufacturer driver specs/box specs for that sub.
