KS-DR2004D 4-Channel Compact Digital Amplifier (600W) for Car, Marine, UTV & Motorsport Vehicles, Solid Corrosion-Resistant Aluminum Chassis, IPX6, IPX7 & IP6X Certified and Vibration-Proof

FOR CAR, MARINE, UTV & MOTORCYCLE - Enhance the clarity of a basic sound system on land or water with the KS-DR2004D 4-Channel Digital Amplifier. With twice the power of comparable units, at 600W (50W x 4), experience superior sound quality for your preferred music. BUILT TO LAST - The Corrosion-Resistant Aluminum Sealed Chassis and stainless-steel screws provide excellent durability, while the Drain Tunnel Structure creates a space between the amplifier and the mounting surface to prevent buildup of saltwater and sand. WATERPROOF, DUSTPROOF & SALT-SPRAY RUSTPROOF - Certified to IPX6, IPX7 & IP6X standards, the amplifier is shielded from strong water jets up to 12.5m, immersion up to 1m, and the entry of dust. The ASTM B117 salt spray (or salt fog) test confirms protection against corrosion. DAMAGE PROTECTION FROM VIBRATIONS - The amplifier undergoes a 3-axis multi-frequency vibration test to verify its capacity to withstand vibrations. The amplifier mounting area is constructed from 15/64 inch die-cast material to minimize the amplification of vibrations. DISTORTION-FREE AUDIO - The premium PMLCAPs (Polymer Multi-Layer Capacitors) decrease distortions, enhancing the overall audio quality even at louder volumes, while the magnetic shielding for the output coils lowers radiated noise for precise sound
