Description

New Infinity Reference amplifiers deliver pure power from a slim, compact chassis that’s designed to fit in more vehicles. Reference amps incorporate our latest amplifier topology, include variable electronic crossovers and bass boost control for precise system tuning, and feature high- and low-level inputs for easy interface with virtually any system. They’re also compatible with several new vehicle technologies, including many advanced driver assistance systems, and Harman HALOsonic, a suite of acoustic solutions that can simulate engine sounds for a better driving experience in hybrids and electric cars, cancel road noise for better-sounding music, and more. In The Box: 1 amplifier High-level input wiring harness 2 spare fuses 2 2-color brand stickers Quick start guide Signal-to-Noise Ratio >80dB (ref 1W output @ 4Ω) Max Power - 1300W Peak System Specifications Power Output, 2Ω - 550W RMS x 1, <1.0% THD+N Power Output, 4Ω - 370W RMS x 1, <1.0% THD+N Infinity Reference amplifiers are designed with a compact chassis and small footprint to ease installation, even if available space is limited.
