This little guy churns out 100 watts of audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms. Rated Continuous (RMS) Power @ 14.4 V@ 4 Ω 75 W RMS x 4@ 2 Ω 100 W RMS x 4Bridged @ 4Ω 200 W RMS x 2 Rated Continuous (RMS) Power @ 12.5 V@ 4 Ω 60 W RMS x 4@ 2 Ω 90 W RMS x 4Bridged @ 4Ω 180 W RMS x 2 General Specifications Frequency Response 12 Hz - 22 kHz (+0, -1dB) S/N Ratio, referred to highest rated power >104 dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth) S/N Ratio, referred to 1 W >84 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth) Damping Factor @ 4 Ω >150 / 50 Hz Damping Factor @ 2 Ω >75 / 50 Hz THD+N @ Rated Power
