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. Pioneerís 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 amplifierís 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.Built-In Crossover (40~500Hz Variable Low-Pass or High-Pass)
Built into the GM-D9500F is a very smart crossover network. This optimizes your system's efficiency and delivers the best possible sound quality.Speaker Level Inputs
What, you DON'T own a Pioneer headunit? Well, we won't hold it against you. In fact we'll even help you build onto your system. The GM-D9500F's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.
