JL Audio RD400/4 4 Channel Class D Amplifier 400W

4 Channel Class D 400WRMS Amplifier

The RD400/4 is capable of pushing out up to 100 watts of clean power to 4 channels at 2 ohms, this amp has the flexibility to push your cabin speakers, your subwoofers, or a combination of them depending on your needs. The RD multi-channel amps have built-in 12 dB/octave low-pass filters and three turn-on modes: Traditional 12-volt trigger, signal sensing and DC offset. Top off the package with a sleek, single-cast piece of aluminum in black powdercoat and blue LEDs, and your power looks as clean as it sounds.

JL Audio’s engineers had professional and at-home installers in mind with the RD Series. All of the inputs and controls are on the same side of the chassis, simplifying the setup whether you’re in a shop or in your driveway. The output clipping indicators on each channel section mean you don’t need specialized tools to accurately set the gain. A remote level control input gives you the option to install a bass level knob, sold separately, in the front seat, giving you full control over the bass output for every song you play.

The RD Series also incorporates JL Audio’s NexD Switching Tehnology. Since Class D amplifiers have a tendency to produce distortion at some ranges, NexD Switching helps cancel it out before feedback is ever applied. All of this helps ensure the some of the cleanest possible signal to your subwoofer and speakers from your brand new Class D amplifier.
