I think your approach is slightly different here. Adding IB to basic sound system means ruining your sound system with a single source of sound from your back which overcomes other frequencies.

You approach should be opposite to find out if you really need IB after installing the sound system. IMHO, sound upgrade on BMW is 'necessity' where adding a sub to upgraded sound system is 'luxury'. Exception is, if you go for alpine retrofit kit where underseats should be upgraded or solo sub in the boot should be fitted. Which approach you take, totally depends on your, your resources and recommendations of your installer.
