Aftermarket speaker impedance question

I have an e91 pre LCI with the base professional audio package (euro spec - 6 speakers, no amp, no Nav)

Is the professional HU 2Ohm stable? If not how is it that it runs the mids and underseat woofers in parallel at 4Ohm each? Does it have something to do with the cap fitted to the factory mids?

Is there a way to replace the factory mids with components and still be connected directly to the HU in parallel with the underseat woofers - or is a 2Ohm stable external amp mandatory for that arrangement?
