JD amplifiers apply our core amplifier technologies and a generous feature set to deliver fantastic value. The amplifier section is 100% JL Audio, with our exclusive NexD™ switching technology for superior fidelity and efficiency. The latter reduces heat output, making the compact dimensions of the JD amplifiers possible.

Features include automatic turn-on capabilities (via signal sensing and DC-offset sensing) and dual-range differential-balanced inputs to combat noise and maximize compatibility with a wide range of signal types. Easy-to-use LED clipping indicator rings surrounding the input sensitivity controls streamline the input level setting process. 12 dB/octave filters are fully adjustable from 50-500 Hz. Monoblock models also include a bass boost EQ and a port for an optional RBC-1 controller to adjust the subwoofer level from the driver's seat.
