You could put the model number or part number for the amp into a search on the open internet and you would be able to verify that .
If you need absolute further proof . Disconnect amp connector an use the wiring diagram at the beginning of this thread and use an ohmmeter to verify the wire runs
to the speaker.

Well…, just so you know… I found out my answer last night… it’s a two channel Harmon/Becker amp (40 x 2) powering the underseat woofers, and the rest of the speakers are powered by the head unit
Not that it necessarily applies to the E90 but BMW obviously DOES change up
Meh
Thx anyway… back to the drawing board
