JL Audio® Source Unit Adaptor Plate for MediaMaster® MM55 and MMR-40 (MMP-2-BK)

This mounting adapter plate allows you to install a compatible MediaMaster® source unit into existing source unit openings that are larger than required (up to 8.17 x 3-inch/208 x 80 mm). The mounting adapter plate provides a solid surface to mount your MediaMaster in locations previously occupied by other marine manufacturers’ source units.\r\n
\r\nFeaturing a durable, black anodized finish that’s both UV- and corrosion-resistant, the mounting adaptor plate 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 source unit for a clean and uncluttered look.
