Rockford Fosgate M2-300X4 Marine 300 Watt 4-Channel Element Ready - Amplifier

Designed to withstand the elements, the M2-300X4 Element Ready amplifier is a 300 watt, full-range class-D model, capable of operating at 4 or 2 stereo, and 4 bridged/mono. This amplifier is extremely efficient because of its class D technology which reduces demand on the electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. Supply that generates more power as voltage increases.

The M2 Series were developed for marine audio environments that feature UV resistant protection and special internal conformal coating that protect the electronics from water. Its designed for those who want a reliable amplifier with all the power and performance youve come to expect from Rockford Fosgate at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being under rated, easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of M2 Series amplifiers are also designed to be easy to setup and configure, making them perfect for use in any application.
