Compact Yet Powerful Amplification

The JVC KS-DR1004D delivers powerful sound in a small footprint, making it ideal for cars, motorcycles, boats, and powersports vehicles. Despite its compact size, this Class D amplifier outputs 45W RMS x 4 at 2–4 ohms or 90W RMS x 2 when bridged, providing flexible installation and strong audio performance for a wide range of systems.

Built Tough for Harsh Environments

Designed for marine and motorsports applications, the KS-DR1004D features a conformal coated PCB to resist damage from salt spray, condensation, and moisture. Its rugged construction ensures long-lasting durability in open-environment conditions, whether installed on the water, the trail, or the road.

Precision Sound Control & Quality

This amplifier incorporates separated pre-amp and power-amp circuit boards to reduce noise, delivering clean, distortion-free audio even at high volume. With variable HPF and LPF filters (50Hz–200Hz), you can fine-tune your system for precise sound adjustment, while a large LPF coil provides stable, high-quality bass response.
