JL Audio MMP-2-BK Mounting Adapter Plate allows you to install a JL Audio MediaMaster MM50 or MMR-40 receiver into an opening that once housed a larger marine radio. It’s constructed from a single piece of marine-grade, machined aluminum, with a black anodized finish that will resist UV rays and corrosion.
The plate comes with stainless-steel hardware and a full-surface gasket to ensure a secure and watertight installation. The countersunk mounting holes are concealed behind your MediaMaster’s trim ring for a great-looking installation.
