JL Audio RD400/4 4-channel car amplifier — 75 watts RMS x 4
$359.99
4-Channel Class D Full-Range Amplifier, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω – 14.4V
Utilizing our exclusive NexD high-speed switching technologies, the ultra-compact RD400/4 amplifier is engineered to deliver loads of audio output power, with incredible efficiency and low distortion. Don’t let its modern styling and small size fool you though, this little powerhouse churns out 100 watts of crystal-clear audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms.
For your convenience, the RD400/4’s controls can be found on top of the amplifier, beneath a protective cover, with all connections located along one side of its chassis. Studio-grade signal processing features include high or low-pass 12 dB / octave filters (defeatable) for each channel pair, with continuously variable frequency selection from 50-500 Hz, and dual-range, differential-balanced inputs capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment, along with all-new input type switches for bridging of stereo output channels without needing to use Y-adaptors.
Onboard LED-clipping indicators are also included with your RD400/4. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity settings, quickly and accurately, with no special equipment needed. You’ll also find a set of preamp outputs on-hand, so you can pass signals to another amplifier, almost effortlessly. The RD400/4 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition.

Car AmplifiersJL Audio HD Series HD900/5 5-channel car amplifier — 100 watts RMS x 4 at 4 ohms + 500 watts RMS x 1
0 out of 5(0)5-Channel Class D System Amplifier, 100 W x 4 + 500 W x 1
Thanks to its ability to act as a “one-box solution”, the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.
While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system… with a very serious 900 watts of power!
Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price.
This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

JL AUDIO – XD1000/5V2 5 Ch. Class D System Amplifier, 1000 W
0 out of 5(0)5-Channel Class D System Amplifier, 100 W x 4 @ 2 ohm + 600 W x 1 @ 2 ohm – 14.4V
The XD1000/5v2 delivers up to 1000 W of clean power and is ideal for an audiophile-grade, subwoofer + four satellite system. With this potent amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 @ 4 ?), while also delivering a stout 600 W of power to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD switching amplifier design.
The XD1000/5v2 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz. This amplifier’s filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on Ch. 3 & 4, and a high-pass filter on Ch. 1 & 2. An “x10” multiplier switch on the Ch. 1 & 2 high-pass filter allows its cutoff frequency to be adjusted from 50-500 Hz or 500-5000 Hz.
The XD1000/5v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier’s level can be directly controlled from the driver’s seat.
This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls.
