AUDIOFROG A600.1D Mono Subwoofer Amplifier — 600 watts RM x 1 at 2 ohms

Product Description:

The Audiofrog A600.1D is a high-performance mono Class D subwoofer amplifier designed to deliver precise, high-current power in a remarkably small chassis. Built on the same “HiFi Class-D” architecture as its multi-channel counterparts, it utilizes high-speed switching and a robust power supply to ensure tight, musical bass reproduction. Its differential input stage is a standout feature, engineered to eliminate induced noise and ground loops—crucial for maintaining signal integrity in the high-noise environment of modern vehicles.

Product Features:

• Optimized Subwoofer Control: Designed specifically for low-frequency duty with a dedicated low-pass filter and a variable subsonic filter to protect subwoofers from over-excursion.
• High-Speed Modulation: Moving the switching frequency well beyond the audio band allows for a smaller output filter and better damping, resulting in “faster” and more accurate bass response.
• Differential Balanced Inputs: Rejects common-mode noise on the signal cables, ensuring that the only thing amplified is the music, not the alternator hum.
• Compact Footprint: The high efficiency of the Class-D design allows for high power output with minimal heat, making it easy to hide under seats or in side panels.
• EMI Shielding: The aluminum housing is engineered to act as a Faraday cage, preventing the high-frequency switching of the amplifier from interfering with the vehicle’s radio or sensitive electronics.
• Multiple Turn-On Options: Includes DC Offset and Signal Sensing modes, allowing for seamless integration with factory (OEM) stereos without a traditional remote turn-on wire.
