MB Quart Marine Amplifiers are designed to conform to the American Boat and Yacht Council (ABYC) marine electronic standards. They feature gold-plated power, ground, speaker and RCA connections. Heat sink enclosure, paint and silk screening are UV and salt water resistant. Marine-grade conformal coated circuit boards are used to resist corrosion from salt spray and moisture. A non-corrosive brushed aluminum extrusion provides an attractive surface finish.
