BMW M4 CS Harman Kardon Replacement

Another BMW leaving the Audiofile-Incar with a System 3 Plus from Optical HK and the Party Sub. This is a killer system, unbelievable power and sound quality, we have an identical system in a demo car if you fancy a visit and a listen.

Surely the entire point of the CS was the 32kg that BMW stripped out? I'm curious to know how much weight this has now added in. Not knocking the work looks top notch as ever, it's a little weird to mess with the entire USP of the car and presumably sink its resale value as well.
