Infinity REF-4555A High-Performance 5-Channel Car Amplifier

• 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 circuits 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.

• Compact footprint: With it becoming more and more difficult to find spacious locations for amplifier mounting, Infinity Kappa amplifiers have been developed in a small compact form factor to allow more location versatility. 

• 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.
