Pioneer GM-D8400M Class-D Mono Amplifier with 1200 Watts Max. Power

Same Powerful Output from a More Compact Amp
100 % of the power, 45 % of the size
The superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers.

Efficiently Compact, Awesome Power
Class-D amplifiers overcome the inefficiencies of traditional Class-A or AB amplifiers. Pioneer’s Class-D amps transform very little power into heat so a higher percentage of the power supply (67%) is transformed into the load. This results in a very compact amp which needs less input power to produce very high output power. The Class-D amplifier’s PWM (Pulse Width Modulator) modulates the original audio input signal with a triangulated signal wave which has a much higher fixed frequency. The result is a digital signal which contains both the input signal and a band of frequency components around the modulation frequency. A LPF (Low Pass Filter) then filters out the high frequency pulses and the resulting amplified output signal is then sent to the subwoofer and/or speakers.

Selectable 50Hz Bass Boost
Bass boost gives you more control over how your music sounds. It lets you set the optimal bass level for each speaker/sub connected to the GM-D8400M, so the tone controls from your headunit can do what they do best. And because this is selectable bass boost, you can set the level at 0dB, 6dB, or 12dB, whichever sounds best to you.

Built-In Crossover (40~240Hz Low-Pass Filter)
Built into the GM-D8400M is a very smart crossover network. It works like a gateway, routing the big bass signals (adjustable from 40 to 240Hz or lower, at -12dB/octave) and filtering out higher-frequency signals to that subwoofer. This optimizes your system's efficiency and delivers the best possible sound quality.
