Automotive 4 Channel Amplifiers

JD-Series 75-Watt x 4-Channel Class-D Full-Range Amplifier Utilizing JL Audio's exclusive NexD™ high-speed switching technologies, the JD400/4 amplifier is engineered to deliver loads of clean power, with excellent efficiency and low distortion. This little guy churns out 100 watts of 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. The JD400/4’s controls can be found on the input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminum chassis. 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 line-level or speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment. Onboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenient feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier.

XDM-Series Four-Channel Class-D Marine-Grade Amplifier, 100-Watts x Four-Channels @ 2-Ohm or 75-Watts x 4-Channels @ Four-Ohm The ultra-compact XDM400/4 packs a serious full-range punch, generating a whopping 100-watts to each of its four channels into 2-ohms (14.4V, 1% THD). The technology that makes this much power possible in such a compact chassis is our advanced NexD high-speed switching design, which permits full bandwidth Class-D operation with extremely low distortion and remarkable efficiency. Suitable for car or boat installations, the XDM400/4 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades. Combine the XDM400/4 with our XDM600/1 monoblock to build a stunning 1000W amplification system to power four satellites and a subwoofer... and fit the whole thing under a seat or deck. Or, use the XDM400/4 by itself to power two satellites, plus a subwoofer.  The XDM400/4 includes a 12dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), you have the ability to adjust the level of all amplifier channels or just the rear channels directly from the driver's seat or cockpit. Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
