Pioneer GM5300T Review:   A really good amp doesn't just provide power. It also offers options for customizing the sound in your vehicle. The 2-channel GM-5300T provides a selectable 50Hz bass boost and a built-in crossover for fine-tuning your tunes. Plus, it comes with speaker level inputs for easy connection to an OEM head-unit.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-5300T, so the tone controls from your head-unit 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 into the GM-5300T is a very smart crossover network. It works like a gateway, routing the big bass signals (80Hz or lower, at -12dB/octave) to the speaker that handles them best, filtering out higher-frequency signals to that speaker. This optimizes your system's efficiency and delivers the best possible sound quality.The GM-5300T'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.

Pioneer GMD7400M Review:   The superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers.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.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-D7400M, 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 into the GM-D7400M 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.The GM-D7400M'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.
