4-Channel Class D Marine Full-Range Amplifier
100W x 4 @ 2Ω - 14.4V
75W x 4 @ 4Ω - 14.4V
200W x 2 @ 4Ω - 14.4V (bridged)
This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its four channels into 2 Ω (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 cut-off 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.
