JL Audio M400/4 : 4ch Marine Amplifier, 4ch x 100W or 75W RMS @ 2Ω or 4Ω - Discontinued

Description

M-Series 4-Channel Class-D Full-Range Marine-Grade Amplifier, 75-Watts x 4-Channel 4-Ohm

This tiny amplifier packs a serious full-range punch, delivering a staggering 100W to each of its four channels into 2Ω (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small chassis is JL's 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 JL's M600/1 monoblock to build a 1000W 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 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 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.
