JL Audio's JD Series Amplifier
The youngest brother in JD Series amplifiers, the JL Audio JD250/1 can still maximize your subwoofer's potential thanks to its Class-D amp design technology. This mono subwoofer amplifier is equipped with JL Audio's own patented technologies and has a compact chassis, so not only do you get a high-quality bass output from it, but you won't also have a hard time installing it in your vehicle.
NexD Switching Technology
The amplifier is equipped with the famous NexD Switching technology, which uses a self-oscillating modulator to help remove the noise that comes from fluctuations in power supply voltage. JL Audio’s JD250/1 is also loaded with differential-balanced inputs, which also cancels out the noise that comes from the usual car audio system wiring setup.
Power Handling
The JL Audio JD250/1 can deliver a power output of 150 Watts at 4 ohms and 250 Watts at 2 ohms. With a frequency response of 7 up to 500 Hz, you get not only a loud bass output but also a deep and extensive low-frequency performance with minimal distortion.
Variable Low-Pass Filter
This mono amplifier also has a variable low-pass filter that can be set from 50 up to 500 Hz and a bass boost control of up to 12 dB at 45 Hz. With JL Audio JD250/1’s features, you can get the more defined bass quality that you deserve.
