This amp model supports both impedances: 2 & 4 ohms.
With 2 ohm subs you will have more power (approx. + 20%).

So... it's your choice.

+1

I could do with some tweeters as well, disappointed BMW don't include them as standard!

what's the question.

It really depends how you plan to install these and what system you had to begin with.

All BMW speakers are normally 4 ohms. However the door and the tweeters (or subs) are connected in parallel thus giving 2 ohms effective. The original subs are 2 ohms when directly connected to the hi-fi amp.
