JL Audio, Inc. 5-Channel Class D Marine System Amplifier, 75 W x 4 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V M700/5

The M700/5 is ideal for a complete audiophile-grade, subwoofer + four satellite system, and it fits comfortably in just about any boat's weather-tight compartments. 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 î©), while also delivering a stout 300 W of power to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexDâ„¢ switching design.
