Well, I finally crawled around back there briefly today. What's odd is that there is actually bass coming out when you crawl into the rear seat/trunk, but it doesn't resonate around the car nearly as much as the front door speakers do. Maybe just a quirky design issue with how the rears are mounted/pointed??!? If there is a sub in the back, it certainly doesn't fire with more percussion than the fronts do, that much I can tell you. I didn't rip cover mount off, however, to check each speaker individually. Still too cold for that.
