As far as i'm aware all E90's and E92's have underseat subs as standard factory fit. These are effectively replacements for them.
If you mean fitting these into another car, then yes it is possible, however i'd hazard a guess that you'd need a custom or generic 'off the shelve' subwoofer enclosure to accomodate these.
