JL Audio JD250/1 JD Series 250W RMS x 1 at 2 Ohms Class-D Monoblock Subwoofer Car Amplifier

Compact Class-D Amplifier Design

The JL Audio JD250/1 is a monoblock subwoofer amplifier designed to deliver powerful bass performance in a compact chassis. Its efficient Class-D amplifier technology helps maximize subwoofer performance while making installation easier in a variety of vehicle audio systems.

NexD Switching Technology and Noise Reduction

Featuring JL Audio's NexD switching technology, the JD250/1 uses a self-oscillating modulator designed to help minimize noise caused by power supply voltage fluctuations. Differential-balanced inputs also help reject unwanted noise commonly introduced through vehicle audio wiring, supporting cleaner signal reproduction.

Powerful Bass Output

The JD250/1 delivers 150 watts RMS at 4 ohms and 250 watts RMS at 2 ohms, providing flexible power options for compatible subwoofers. With a listed frequency response of 7 Hz to 500 Hz, this amplifier is designed to reproduce low-frequency audio for a strong, detailed bass experience.

Adjustable Low-Pass Filter and Bass Boost

Customize your subwoofer's sound with the variable low-pass filter, adjustable from 50 Hz to 500 Hz. The bass boost control provides up to 12 dB of boost at 45 Hz, allowing you to tailor low-frequency output to your listening preferences and audio system setup.

Flexible System Integration

The JD250/1 can be integrated into compatible aftermarket audio systems and accepts high-level speaker inputs when installed using the appropriate wiring. Its dedicated monoblock design is intended for subwoofer applications, and an optional HD-RLC remote bass control can provide convenient bass level adjustment from the driver's seat.
