This JVC KS-DR1004D marine 4-Channel amplifier has a maximum power output of 400 watts and flaunts Class D amplification technology, providing you with a powerful interface for your vehicle's audio system. A conformal coating is a protective chemical coating to safeguard electronic circuits from harsh environments that may contain moisture or chemical contaminants. It provides a barrier to airborne contaminants from the operating environment, such as salt-spray, thus preventing corrosion. Separated circuit boards of the Pre-amp and Power-amp sections contribute to a reduction in radiation noise.
