I am looking at upgrading my speakers ( just the mids and tweeters for now). From what I see I have the s677 hifi professional dsp system,are they just 4 ohm speakers which means I can go with any speakers that fit or am I missing something? I don't want to remove door panels to look as I hear the clips break so I would rather have new speakers on hand and remove it only once.

They are a BMW specific moulding pattern…cheapo solution is to get some adapter rings…
For a 677 system ideally you should be looking at Audiotec Fischer, Eton or Audison plug n play versions…
In most cases you will need to cut a hole in the plastic recess that sits in the inner door skin to get the bigger magnets to clear..
