These baffles when installed with Kenwood KFC-1665S speakers in the rear door panel muted the distortion caused by bare metal behind the speakers in a Chevy HHR. Sound was crisp and clear after the baffles were installed.

They are baffles, help deaden the sound from inside the door and keep speakers free from any water infiltration. Also helpful as a gasket, so no vibration from the speakers. I would only use these in doors, not for deck speakers as you lose some bass response.
