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.
