Can't say for sure as I do not know what changes were made for the 2 series, but on older BMWs with seat subs, it took a dremel to flatten some ridges on the holder and a foam gasket. There is an install video on youtube.

Biggest issue is that the system is probably 4 ohm and the earthquakes are 2 ohm. Mismatch will likely kill amp. Therefore a small amp for the subs would be better.
