JL Audio Source Unit Adaptor Plate - MediaMaster MM105

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.

Featuring a durable black anodised 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.
