I've tried it, but there are too many controls for me☹️ You need to have a basic framework first and then refine it as you like😉
Nevertheless, what can actually be achieved with the HIFI chassis? Is replacing the speakers mandatory?
Does changing the cables help in the Bimmer, even if the plug connections are the bottleneck?
Cables are not the bottleneck. You don't have to worry about that.
