Ironically this is the truth in every high end car. Despite being astronomically priced the customer gets this skimpy, cheap driver based ICE.
Manufacturer uses cheap quality drivers. Their engineers work on designing the pods and acoustics to get best out of them. They save huge costs like this.
Even companies like Bose etc use cheapskate drivers and uses their expertise on loading and acoustics etc to get the best out of them. The customers see Bose logo flanked on the door pad which gives him satisfaction of having a good ICE, because manufacturer knows that typical customer will never see what went behind the door pad. The one who knows will never pay hefty price for Bose and other similar expensive ICE options, sadly there are not many of those kind in India

.
It is the case with every car of Mercedes, BMW, Porsche, Bentley, Lamborghini, Ferrari, Audi etc.
There are very few cars with decent OE soundsyatem like VW Passat, Volvo C90 (Dynaudio), Lexus SC 430(Mark Levinson), Aston Martin Vanquish (Linn) and Audio A8 W12 (B&O) but again they are very expensive options and you can do far better in less money.
I remember we went to S Class launch in Delhi. They were showcasing S500 with HK Logic 7 system with expensive rear entertainment system. The guy who handled the design was there saying all the good things about the system claiming the best sound and works next to him standing was MR. Aulbur, CEO of Mercedes Benz.
We told him its great but tell us one thing how do we control the volume of the system sitting in the back seat in the car with rear entertainment system. The silence and look on the guys face gave us the answer that there is no volume control for rear passengers. The owner has to tell his chauffer to control the volume, Intelligent. We smiled and walked out of the car.
These are the things which will never be noticed by the owners as they are nostalgic of getting the cars opened for aftermarket ICE to improve the sound.
I have seen so many cars at the workshop in which the speakers have gone surroundless as foam surround has deteriorated over the period of time. But the guy is still driving around with that car listening to the speakers.
Check the Ferrari Install and see the condition of speakers in the car. Thats a common sight in High End cars here.
