JL Audio MMP 1 BK MediaMaster Mounting Adapter Plate - 8.67 x 4.22 Inch Universal Car Stereo Installation Kit for Seamless Audio System Upgrade

The MMP-1-BK mounting adaptor plate allows you to install a MediaMaster® MM100s into existing source unit openings that are larger than needed for the MM100s (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® MM100s 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 MM100s for a clean and uncluttered look.
