Pioneer GM-D9500F Car Class-FD 4-Channel Bridgeable Amplifier

Features

• 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.
• 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 systems efficiency and delivers the best possible sound quality.
• Speaker Level Inputs:  What, you DONT own a Pioneer headunit? Well, we wont hold it against you. In fact well even help you build onto your system. The GM-D9500Fs speaker level inputs allow you to connect your OEM unit (or any unit that doesnt have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and youve got a Pioneer amp in your vehicle.
