No. Setting to front averages (effectively disables) time alignment for the front seats
Dont pay too much attention to the volume of the center. Instead listen to placebt of instruments and voices across your windshield.
I can listen to a band and hear the vocalist dead center, guitars on either side of that (in front of each seat lets say) kick drum dead center and drum rolls across the windshield. Thats why you want time alignment for your seat.
