most cars with pillars or dash mounted drivers have a reflection on the drivers side window
think how we hear, we get the location of a sound source from all sources of sound, so if you have strong reflections from the side window and above the driver then we will ‘hear’ the source of the sound as being outside the speaker towards the side window…
and also the passenger side we hear the sum of all the sound sources… it’s not uncommon to hear the passenger side several inches in from the pillar or speaker location…
so we can have two sources of sound that are over to the left… what will that do to your centre if it is timed correctly and between left and right as our brain decides there location? Just what you experience
people get hung up on the centre of the car being the centre, work out where your stage boundary’s are and then work out where the centre should be located… it’s likely not the centre of the car!
as for the phase, don’t get hung up on worrying about phase wraps above midranges and somewhere around 2khz, tbh I only tend to use all pass below 1khz max, installation location of drivers to get clean phase is far more important in the first instance
clean phase between two drivers gives depth of stage, along with correct eq work and freq response
