New Infinity Reference amplifiers deliver pure power from a slim, compact chassis that’s designed to fit in more vehicles. Available in 4-channel, 5-channel, and mono models, 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
Product Features:
  • Compact footprint
    Infinity Reference amplifiers are designed with a compact chassis and small footprint to ease installation, even if available space is limited.
  • High- and low-level inputs
    Speaker-level and low-level inputs allow Reference amps to work with just about any car stereo, aftermarket or factory.
  • Variable crossovers and bass boost
    Unlike many amplifiers available at similar prices, Reference amps feature variable electronic crossovers and bass boost circuit to allow for fine-tuning.
  • ADAS input with channel assignment
    In vehicles with ADAS warning systems, you can assign a channel to broadcast system alert messages.
  • HALOsonic mixing input
    Reference amps can also work with the HALOsonic systems of select vehicles, which helps reduce external noise for a better sonic experience.
