High-Performance 4 Channel Amplifier

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.

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.
