This is the 6.5-inch (165mm) aftermarket audio upgrade speaker adapter and spacer ring pair, custom-engineered for Renault Megane models. Designed to sit perfectly flush against the original door sheet metal and panel aperture, these mounting rings ensure the new speaker chassis fits securely without chafing or wearing against raw metal panel edges or window tracks.
