JVC KS-DR2004D 4-Channel 200 Watt Compact Digital Amplifier for Compact Car, Marine, UTV and Motorcycles

IPX6: Protection against Powerful Water Jets / Water projected in powerful jets, up to 12.5mm (0.49 inch) against the amplifier from any direction shall have no harmful effects. IPX7: Protection against Immersion, up to 1 m (3 feet, 3 inch) depth / Restricts harmful amounts of water entry when the amplifier is immersed in water under defined conditions of pressure and time, up to 1 m (3 feet, 3 inches) of submersion. IP6X: Effective against Dust-tight / Dust entry is restricted to avoid damage to the amplifier. A Drain Tunnel Structure is employed for creating a gap between the amplifier and the installation surface. This prevents saltwater and sand from accumulating on the bottom, increasing corrosion protection. Thicker terminal connection points and increased wire size enables maximum current flow and higher output for better low frequency response and cleaner output. High Quality PMLCAP’s (Polymer Multi-Layer Capacitors) are utilized to lower distortion levels, improving the overall listening experience at higher volumes, while maintaining the integrity of the sound. Magnetic Shielding for the output coils reduce radiated noise, delivering smooth and accurate sound.
