GM-6400F specifications

The Pioneer GM-6400F is a versatile four-channel power amplifier designed to provide a significant boost in sound quality and performance for car audio systems. This robust amplifier is engineered to enhance your listening experience by delivering clear and powerful audio reproduction.

One of the main features of the GM-6400F is its impressive power output. With a maximum power of up to 640 watts, this amplifier is capable of driving multiple speakers without distortion, ensuring that every note and beat is delivered with precision. The GM-6400F can deliver 75 watts RMS per channel at 4 ohms, making it suitable for a wide variety of speakers, and produces a punchy and dynamic sound that can fill any vehicle.

Additionally, the amplifier incorporates advanced Class D technology, which contributes to its efficiency and compact size. Class D amplifiers are known for generating less heat compared to traditional Class AB amplifiers, allowing the GM-6400F to utilize a smaller chassis without sacrificing power or performance. This enables easier installation in tight spaces without compromising sound quality.

The GM-6400F also features a built-in low-pass filter that allows users to tailor the sound to their preference. This filter can be adjusted to focus on specific frequencies, making it easier to blend with subwoofers or enhance specific elements of the audio mix. Furthermore, the amplifier provides a variable bass boost which can add extra thump to low frequencies for those who desire a more pronounced bass experience.

With its durable construction, the Pioneer GM-6400F is built to endure the rough conditions of a mobile environment. The amplifier’s sleek design ensures not just performance but also aesthetic appeal, making it a great addition to any audio setup. An easy-to-read LED indicator on the front panel helps monitor the amplifier’s status without the need for complex diagnostics.

Overall, the Pioneer GM-6400F is an exceptional choice for car audio enthusiasts seeking a powerful yet efficient amplifier. Its combination of advanced technology, user-friendly features, and robust build quality makes it a top contender for enhancing sound in any vehicle audio system. Whether you’re listening to your favorite music or experiencing cinematic sound effects, the GM-6400F is designed to elevate your auditory experience on the road.
