JL AUDIO MMP-2-BK: MediaMaster® Mounting Adaptor Plate for MM50 & MMR-40 Retrofit | 99929

The MMP-2-BK mounting adaptor plate allows you to install a MediaMaster MM50 or MMR-40 into existing source unit openings that are larger than needed (up to 8.17 x 3-in/208 x 80 mm). Constructed from a single piece of marine grade, machined aluminum, the MMP-2-BK provides a solid surface to mount your MediaMaster MM50 or MMR-40 in locations previously occupied by other marine manufacturers source units. Featuring a durable, black anodized finish that’s both UV and corrosion-resistant, the MMP-2-BK includes stainless steel hardware and a full surface gasket to ensure a secure and watertight installation. Panel mounting holes are countersunk and thoughtfully positioned to keep them concealed behind the trim ring of the MM50 or MMR-40 for a clean and uncluttered look.
