Yeah you'll need 4 cubes after sub and port displacement

Right^^^ and just in case, allow me to elaborate... Displacement is the space your subs as well as the port in your box use up, so your box may need to be 4.75 cubes before displacement (example) .. And of you need to know what your sub displacement would be for each sub you can find that in sub specs.. Good luck
