Components have a better crossover network but untrained ears will never notice. The door speaker height is a contributory factor in speaker location. If your coaxials have a tweeter that can be rotated make sure it's as high and rearward as possible, same with components. If possible, mount the component tweeter as coaxially centered as possible to the midbass driver. The soundstage would be considered to be where the rearview mirror is. You're not going for SQ or a perfect soundstage so use what fits but don't cheap out.
