Mud, Sand, Dirt, Rocks or Water — The JVC KS-DR2004D is BUILT TO LAST.
IP67/IP66 Waterproof & Dustproof
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.
Dust Tight
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.
ASTM B117 Rustproof
Saltspray-proof: ASTM B117 salt spray (or salt fog) corrosion test simulates harsh conditions in a saltwater environment to ensure the amplifier does not corrode or fail in these harsh conditions.
By adopting the Corrosion-Resistant Sealed Cast Aluminum Chassis and stainless-steel screws resistant to rust and corrosion, this amplifier achieves the highest level of durability in its class.
Vibration-proof
Vibration-proof: Vibration can be damaging to amplifier if it is not designed to withstand it. This amplifier passes a 3-axis multi-frequency vibration test.
15/64 Inch Die-Cast Material
The amplifier mounting section is made of 15/64 inch die-cast material to suppress the amplification of vibration. In addition, the thick heat-transfer sheet was also placed to the substrate and the Aluminum die cast heat sink to suppress the vibration of the substrate.
Sound Optimization
SOUND QUALITY is Never Sacrificed.
Increased Power Flow
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 Capacitors
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
Magnetic Shielding for the output coils reduce radiated noise, delivering smooth and accurate sound.
Dimensions
KS-DR2004D features compact size for versatile installation even in tight spaces.

KXM Amps 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 controls.
The KXM 400-watt four-channel amplifier is flexible enough to be a full system solution, or serve as the power for your mid and high-range speakers. KickEQ+™ delivers as much as an 18dB of extra bump with a simple turn of the knob, and powerful 24dB crossover is also included to letting you quickly tune your system to perfection.
