<p>Designed to withstand the elements, the M2-300X4 Element Ready™ amplifier is a 300 watt, full-range class-D model, capable of operating at 4Ω or 2Ω stereo, and 4Ω 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.</p><p>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. It’s designed for those who want a reliable amplifier - with all the power and performance you’ve 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.</p><h2>M2 300 Watt 4-Channel Element Ready Amplifier Features:</h2><ul><li>Element Ready™ design protects against outdoor exposure</li><li>Conformal coated circuit board protects against dust and water</li><li>UV stable powder coated cast aluminum heatsink</li><li>Zinc Nickel-plated Marine grade brass connection terminals</li><li>C.L.E.A.N. input/output clip detection and indicator LEDs</li><li>Optimized using AudioGraph PowerCube measurement tool</li><li>Focused mass heat sink allows critical aluminum material to be located around hottest internal devices</li><li>Top Mounted Control Panel</li><li>Fully Adjustable 12 dB/octave High and Low pass Butterworth Crossovers</li><li>2/4 channel input switch</li><li>Short Circuit &amp; Over Current Protection</li><li>Integrated Power and Speaker Terminals</li><li>Balanced Differential Inputs eliminates noise picked up by signal cables</li><li>RCA pass-thru outputs</li><li>Integration with OEM and Aftermarket Radios</li><li>"Auto-Sense" turn-on with remote out (high level in)</li><li>Auto-Sense bypass switch for vehicles with RAP (Retained Accessory Power)</li><li>Low Impedance Stability</li><li>Proprietary testing using RATS (Rockford Automated Testing System)</li><li>CEA-2006 Compliant &amp; CE Compliant</li><li>2-Year Warranty</li></ul><h2>Specifications</h2><ul><li>Number of Channels - 4</li><li>Total Power (Sum of Rated Power) - 300 Watts</li><li>Rated Power (RMS Continuous Power) - 50 Watts x 4 @ 4Ω, 75 Watts x 4 @ 2Ω, 150 Watts x 2 @ 4Ω Bridged/Mono</li><li>Dynamic Power (PVC/PowerCube®) - 70 Watts x 4 @ 4Ω, 115 Watts x 4 @ 2Ω, 230 Watts x 2 @ 4Ω Bridged/Mono</li><li>Bridgeable - Yes</li><li>Frequency Response - 20 Hz - 20 kHz</li><li>Input Sensitivity - Low-Level: 150 mV - 4 V, High-Level: 450 mV - 12 V</li><li>Circuit Topology Class - Class D</li><li>Total Harmonic Distortion (THD+Noise) - 4Ω: </li><li>Signal Input - Front Low-Level: 2 RCA, Front High-Level: 4-Pin Molex, Rear Low-Level: 2 RCA, Rear High-Level: 4-Pin Molex, Input Switch: 2/4 Input (works for RCA/High-Level inputs)</li><li>Signal Output - Low-Level: 2 RCA (Pass-Thru active with RCA or Hi-Level input)</li><li>Tone Controls - No</li><li>Crossover Controls - Front High-Pass: 50 Hz - 250 Hz @ 12dB/Octave Butterworth, Front Low-Pass: 50 Hz - 250 Hz @ 12dB/Octave Butterworth, Rear High-Pass: 50 Hz - 250 Hz @ 12dB/Octave Butterworth, Rear Low-Pass: 50 Hz - 250 Hz @ 12dB/Octave Butterworth, All-Pass: Yes</li><li>Remote Controls - No</li><li>Visual Indicators - Power/Protect, C.L.E.A.N.
