there have been a number of threads on car based sound systems
branding of car audio is just that - branding to sell things, make people spending money feel like they are getting something nice
end of the day, some cars are for thrills, in these you don’t listen much to the car audio, the car provides the soundtrack
other cars are appliances, functional to get you there with minimum of fuss and discomfort, these are more isolation machines, drivers/riders onboard are not trying to connect to the car, they want to enjoy their time despite the car... here car audio systems are more important, some are pretty nice, others not so much - none can compare to a home system though
i find the car audio branding doesn’t correlate too well with sound quality
