I worked at Bose as an Senior Electrical Design Engineer and I will say that besides being a bit biased, one product in particular sounds amazing which is this one right here:
I no longer work there, nor is it a sales pitch, just as FIY as I own a pair of them also.
It all comes down to how the speaker enclosures are set up and placement for sound imaging. In an AS, while I'm sure most won't notice or care, there isn't really a good way to create that space in the roof lines, and metal isn't exactly the proper materials for resonance response of the speaker drivers.
So yeah, almost any "device" meant to deliver portable "good" sound will most likely outpace an AS factory installed system....mostly through no fault of AS.
If they did do it right, the costs would got up for exotic materials that are light weight, low resonance and then trying to shoehorn the volumetric space needed to match the exact Thiele/Small parameters of the speakers that are chosen to go in those spaces.........no one will pay for that......and most will not care......not even addressing the garbage MP3 compressed files or compressed Satellite radios that most will listen too.
TLDR: Yes, I wouldn't be surprised!
