Would anybody know what is the output for the HK in the ZHP? How many total speakers?

Comparing the output from my '24 X4 G02 HK to the ZHP. The sound output seems to be more solid in the ZHP no matter what I do to balance the X4 output. My son said that maybe my hearing is defective....Which I agree....

Although 600W continues to be a typo on the US config BMW website (it should be 464W according to Harman site) for the G02.
