JL Audio – M400/4 4 Ch. Class D Full-Range Marine Amplifier, 400 W
$549.00
4-Channel Class D Marine Full-Range Amplifier, 100 W x 4 @ 2 ohm / 75 W x 4 @ 4 ohm – 14.4V
This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its four channels into 2 ? (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small chassis is our NexD ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.
Use the M400/4 in combination with our M600/1 monoblock to build a 1000 W amplification system to power four satellites and a subwoofer… and fit the whole thing under a seat. Or, use the M400/4 by itself to power two satellites, plus a subwoofer. With M-Series amplifier, the possibilities are endless.
The M400/4 includes a 12 dB / 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 50-500 Hz. With the addition of an HD-RLC remote level control (sold separately), the amplifier’s Ch. 1 & 2 level or overall level can be directly controlled from a remote location.
This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.

0 out of 5(0)5-Channel Class D Car/Marine System Amplifier, 75 W x 4 @ 4 Ω + 300 W x 1 @ 2 Ω – 14.4V
The XDM700/5 is ideal for a complete audiophile-grade, subwoofer + four satellite system, and fits comfortably in just about any vehicle or vessel. With this incredible little amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 @ 4 Ω), while also generating a solid 300 W of power for a subwoofer system. The technology that makes this much power possible in such a small chassis is our high-speed NexD™ switching amplifier design.
Suitable for car or boat installations, the XDM700/5 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.
The XDM700/5 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. 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 subwoofer channel directly from the driver’s seat or helm.
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
