I'm no Bose fan but had one in a Maxima. This had the 4" drivers in front,6X9 in the rear. No tweeters, just full range drivers. Each speaker had its own amp that included an EQ circuit specifically designed for the car. I added a sub and it was quite nice considering what it was. Good mids and very coherent. I think this has to do with just a single driver. Nothing is more offensive to my ears than a driver down on the door on one "plane" and a tweeter up high on a different one.
