Maximum Power Output - Class D amplifiers are capable of delivering substantial power, and the GM-DX871 follows this trend with a maximum power output of 1,600 watts. This robust amplification enables dynamic and impactful sound reproduction. Class D Amplification - These amplifiers are recognized for high efficiency, converting a greater proportion of input power into output power relative to other amplifier classes. This efficient operation leads to minimized power loss and lower heat production. Compact Design - Class D amplifiers are typically more space-saving in size compared to other amplifier classes. The space-efficient design of the GM-DX871 facilitates installation in various vehicles with restricted space and prevents it from occupying excessive room. Variable Low-Pass Filter - For enhanced adaptability, a variable LPF allows for more adjustable audio frequency based on subwoofer characteristics and individual listening preferences. The GM-DX871 LPF is adjustable from 40 Hz to 240 Hz. Protection Control System - This system monitors the input voltage, current consumption, and operating temperature to automatically regulate the amplifiers output, ensuring stability during listening sessions or when installed in high-temperature environments
