JL AUDIO (MMP-1-BK) MOUNTING ADAPTOR PLATE FOR MEDIAMASTER MM105/MM100S - 8.67 X 4.22 IN (220 MM X 107 MM) Mounting Adaptor Plate for JL Audio® MM105 and MM100s Source Unit The MMP-1-BK mounting adaptor plate allows you to install a MediaMaster® MM105 or MM100s into existing source unit openings that are larger than required (up to 8.17 x 3-inch / 208 x 80 mm). Constructed from a single piece of marine-grade, machined aluminum, the MMP-1-BK provides a solid surface to mount your MediaMaster® 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-1-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 source unit for a clean and uncluttered look. In-store Purchase only SKU # 99919
