M135i F20 Code Stereo/Radio Speaker Upgrade

I know this has been covered previously but, various post contradict the process required.

I have recently bought as set of Focal speakers to upgrade the basic stereo setup on my 2013 M135i. My OEM setup included front door speakers, under-seat subs and rear-shelf speakers....no tweeters.

I have fitted focal ifbmw-c to the front doors, ifbmw-v2 subs under the seats and isc100 speakers to the rear.

My questions exactly what coding do I need to change? Do I need to change both audio_system_cic AND audio_system_var and what should I change them to? Previous posts have stated only changing audio_system_cic to Hifi if you have separate tweeters?? And what do each of the 3 variants of audio_system_cic equate to?

With the standard setup there is no low volume bass.

Is there anything else that needs to be changed in coding once the speakers are fitted??

Thanks
