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.

For 24V systems only: 4-Channel Class D Marine Full-Range Amplifier, 150 W x 4 @ 1.5-4 Ω

This compact, multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.

The MHD600/4-24V is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. It can also be deployed, on its own, as a very capable 3-channel system amplifier with 150W x 2 to the satellites and 300W x 1 to a subwoofer system.

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.

This amplifier is designed for operation in vessels with 24 volt, negative-ground electrical systems. Use of this product in vessels with positive ground and/or voltages other than 24 V may result in damage to the product and will void the warranty.

For 24V systems only: 5-Channel Class D Marine System Amplifier, 100 W x 4 + 500 W x 1

Thanks to its ability to act as a “one-box solution”, the MHD900/5-24V 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 marine 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 MHD900/5-24V delivers 100 W x 4 to its four main channels, plus a very meaty 500W 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.
