JVC 4-Channel AmplifierKS-DR1004D
4-Channel Compact Amplifier for Compact Car, Marine, UTV and Motorcycle / Max Power 400W / 45W RMS x 4 @ 4 ohms

The JVC KS-DR1004D is a compact, 4-channel Class D amplifier designed for marine, UTV, and motorcycle applications, featuring a 400W maximum power output and 45W RMS  4 at 4 ohms. It boasts conformal-coated circuit boards for moisture resistance, compact dimensions (), and variable high/low-pass filters (50–200 Hz). 
Key Features & Specs:Power: 45W RMS  4 (4 ohms/2 ohms); 90W RMS  2 bridged (4 ohms).Protection: Conformal-coated circuit board protects against water and salt, making it ideal for harsh, open-air environments.Design: Compact "drvn" series design fits in tight spaces like motorcycle fairings or small car compartments.Filtering: Variable high-pass/low-pass filters (50Hz–200Hz, 12dB/octave) on both front and rear channels.Input/Output: Features pre-amp and speaker-level inputs (requires adapter) with signal-sensing turn-on.Efficiency: Class D technology ensures low power consumption and less heat.Signal-to-Noise Ratio: .
This unit is designed to work with both 2-ohm and 4-ohm speakers, providing versatile installation options for marine or powersports vehicles
Versatile ApplicationReceivers and amplifiers for marine and motor sports applications need to perform in harsh environments exposed to outdoor elements. JVC’s marine and motor sports receivers and amplifiers feature compact size for versatile installation even in tight spaces. Conformal coated main PCBs (printed circuit boards) offer additional protection against moisture and condensation from damaging the product.


Conformal CoatingA 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.


Circuit Separation ConstructionSeparated circuit boards of the Pre-amp and Power-amp sections contribute to a reduction in radiation noise.


Large LPF CoilThe large LPF coil provides stable, high quality sound with no distortion even when playing at high volume.


Variable HPF & LPFIncorporates a rotary type HPF and LPF which enables fine adjustment. Compared with fixed type switching, more precise sound adjustment is possible to match your preferences.
