My F46 has 6 speakers: 4 in four door and 2 bass under front seat, these speaker may connect to NBT and powered by NBT.
I had replaced 4 door speakers, now I wish to upgrade the amplifier and the bass drivers.
How can I start?

If you don't have the dash centre speaker then you only have the base audio system where the speakers are powered by the headunit and not a separate amplifier. Do a VIN decode on MDECODER.COM andlook for the upgraded Audio options 676 or 677 which do have a separate amplifier.
