It’s such a pleasure to drive with a good sound system. With some higher end cars extra technology has gone into this and what a difference it makes, some cars will have 10-13 separate speakers throughout the vehicle. I’ve even experienced some that the volume goes down when the car is stopped and goes up when car in motion! BMW and Audi has this feature. A good test on a sound system is to take the car out on the highway and notice how it sounds in conjunction with road noise.
