An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 hertz to 20,000 hertz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain.
The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification, equalization, tone control, mixing/effects, or audio sources like record players, CD players, and cassette players. Most audio amplifiers require these low-level inputs to adhere to line levels.
While the input signal to an audio amplifier may measure only a few hundred microwatts, its output may be tens, hundreds, or thousands of watts.

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.
