That’s fair enough but people don’t have a flat hearing frequency response and it moves with age so you may want to boost the mids at some point, especially if you are listening to voices rather than music.
I also find that tweeters can be placed too near the driver in certain vehicles, giving you an overly bright sound. Taking down the highs a notch or two then helps.
With a home system your speaker placement can dial out tonal imbalance, you don’t get that luxury in a car.
