GM-X574, GM-X374 specifications

The Pioneer GM-X374 and GM-X574 are distinguished amplifier models that capture the essence of dynamism and versatility in car audio systems. Both models are integral parts of the Pioneer amplifier series, designed to deliver high-performance sound amplification with advanced technological features, making them favorites among audio enthusiasts.

The GM-X374 is a 4-channel amplifier, allowing for versatile installation options in various vehicle configurations. One of its standout features is the compact, space-saving design, which facilitates easy mounting without consuming valuable real estate in the trunk or under seats. The amp boasts a power output of 50 watts per channel at 4 ohms and can deliver up to 90 watts per channel at 2 ohms. This ensures that users enjoy robust sound performance, even at higher volume levels, without distortion.

Pioneer's GM-X574 takes things up a notch with its 5-channel configuration, making it ideal for systems that require additional power for subwoofers. Its power output reaches 50 watts per channel for the four channels and a substantial 150 watts for the subwoofer channel at 4 ohms, ensuring a deep, resonant bass experience. This model is especially appealing to those who want to build a comprehensive sound system without needing multiple amplifiers.

Both amplifiers are equipped with an array of technologies that enhance their performance. The built-in crossover network allows users to tailor the sound output according to their preferences, making it easier to achieve a balanced audio experience. The adjustable high-pass and low-pass filters ensure that the right frequencies are sent to the appropriate speakers, vastly improving audio clarity.

Durability is another key characteristic of the GM-X374 and GM-X574. Both models are constructed with high-quality components designed to withstand the rigors of automotive environments. The heat sink design promotes efficient heat dissipation, allowing for extended use without overheating, thereby ensuring longevity and reliability.

The amplifiers are also equipped with RCA inputs, making them compatible with a wide array of head units. This flexibility allows for seamless integration into existing audio systems. These features, combined with easy installation options and a sleek design, make the Pioneer GM-X374 and GM-X574 excellent choices for anyone looking to elevate their car audio experience.
