Audiophile Marine

Nautic amplifiers are not automotive amplifiers. While they will work just fine in a car or truck, they are purposely built to very strict standards set forth by both the American Boat and Yacht Council (ABYC) marine electronics standards and the American Society for Testing and Materials, ASTM International™. Specific for marine installations the Nautic amplifiers are available in 2, 4, 5 and a 6 channel configurations so you can drive speakers on the deck or in the cabin and have plenty of power for subwoofer channels. It is possible to have “great” sound on the water, the solution is Nautic from MB Quart. More information
