I've never added baffles to my speakers before, but it always felt like I lost a lot of volume through the truck. I added these to my F-250, along with a pair of 6x8 Pyle speakers to replace the OEM speakers. Prior to adding the baffles, the back seat speakers sounded muffled and quiet. The doors were fine, but what little bass that played through was often lost in the door. With the baffles added, the audio throughout the cab seemed to become more balanced and definitely louder. The install was easy and the quality of the material is high. I'm impressed with the difference they made in my listening experience.
