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 - Bring clarity to a basic sound system on land or water with the KS-DR2004D 4-Channel Digital Amplifier. With double the power of its competitors, at 600W (50W x 4), enjoy outstanding sound quality for your favorite tracks. BUILT TO LAST - The corrosion-resistant aluminum sealed chassis and stainless-steel screws ensure high durability, while the drain tunnel structure creates a gap between the amp and the installation surface that prevents the buildup of saltwater and sand. WATERPROOF, DUSTPROOF & SALT-SPRAY RUSTPROOF - Certified IPX6, IPX7, and IP6X, the amp is shielded from powerful water jets up to 12.5 m, submersion up to 1m, and dirt ingress.

The ASTM B117 salt spray (or salt fog) test verifies protection against corrosion. DAMAGE PROTECTION FROM VIBRATIONS - The amp passes a 3-axis multi-frequency vibration test to confirm its ability to withstand vibrations. The amplifier mounting section is constructed from 15/64 inch die-cast material to reduce the amplification of vibrations. DISTORTION-FREE AUDIO - The high-quality PMLCAPs (Polymer Multi-Layer Capacitors) minimize distortions, enhancing overall audio quality even at higher volumes, while the magnetic shielding for the output coils lowers radiated noise for precise sound
