The JL Audio RD400/4 4 channel amplifier is small, sleek and amazingly powerful and versatile.  Using NexD switching technology, this 4-channel car amplifier gives you 100 watts of clear RMS power from each of its four channels. You can also choose to bridge it to produce 3-channel or 2-channel power. That’s what has made this a popular choice for many applications at Audio Express / Quality Auto Sound.

JL Audio has packed the RD400/4 with studio-grade signal processing features such as high or low-pass defeat able 12 dB/octave filters for each channel pair, and dual-range, differential-balanced inputs designed to clean stray noise from the signal. Automatic turn-on, using signal sensing or DC-offset sensing, is standard equipment. Pass-through preamp outputs make it easy to integrate this amp into a system.

The black powder-coated case features all of the controls on top of the amplifier, beneath a protective cover, with all connections located along one side of the chassis. Top-mounted, dual-color LEDs report the overall status and condition. Onboard LED-clipping indicators let you easily set your amplifier’s input sensitivity quickly and accurately with no special equipment needed.
