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. Pioneers 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 amplifiers 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 (40240Hz 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 syst

Fantastic product for the money

"This other guys has an improperly installed amplifier. I have used these in a couple of systems now and it is one of the best values for the money out there. I have used lower end to very high end $1500+ amplifiers in the past so I consider myself a decent judge of quality. Its size is a good bonus …" Read Full Review »

"I'm pleasantly surprised at the performance of this amplifier, especially considering the price. I'm using it to drive one 10" Pioneer TSSW2501S4 shallow subwoofer @ 4 ohms and the bass hits hard and tight. Install was very easy due to the small size of the amplifier. I'm very happy with my purchase …" Read Full Review »

"The amplifier is small, a lot smaller than my previous 960 watt Kenwood, but pushes my subs with about the same power, and great clarity. I'm not winning any noise competitions, but I can feel the bass in my chest. This has never overheated, I would buy it again. "

"I bought this amp because space was a concern. It had to fit in a Lexus GS400, inside the dash, above the glove compartment, where the old CD changer was. No other amp would fit in such a small place so the form factor was good. Since I had a Pioneer head stereo I though matching the make could only …" Read Full Review »
