Kickers marine amplifiers are built for the outdoors. Power, speaker and input connections are gasket-sealed, as is the control cover hiding the settings, creating a water-resistant barrier to key components. The internal circuit board is sprayed with a moisture-deterring conformal coating for water and dirt resistance. The amplifiers power connections meet marine-industry standards for protection against the elements. Stainless-steel mounting hardware prevents rust stains on carpeting and gel coat, and the UV-treated chassis finish battles harsh sunlight.
General Features:
