Class D Design

Every Kappa amplifier, including the full-range models, features a high-efficiency Class D topology. This technology allows Infinity to engineer amplifiers that are more compact, generate less heat, and draw less current from the vehicle’s electrical system.

Low Distortion

Infinity’s Kappa amplifiers have been engineered to deliver the lowest distortion possible, enhancing the audio experience regardless of output level.

Full On-Board Protection

Infinity Kappa amplifiers have onboard circuitry to protect from shorts, temperature, overvoltage, and under-voltage. An LED indicator is included on all five models to let the user know when one of these conditions exists.

Proprietary High-Conductivity Terminals

All Infinity Kappa amplifiers equipped with the newly introduced E.A.R.L terminal for better grounding. The adapter connector is available in the box for easy installation.

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.

Sleek design

Sometimes, an amp can be as stylish as it is powerful. With an anodized aluminum and screwdriver access concealed by a magnetically attached panel, Infinity Kappa amplifiers have a clean, streamlined industrial design.

DBO™ (Dynamic Bass Optimizer)

Kappa amplifiers feature a subsonic filter with variable frequency and Q. For sealed enclosures, set the Frequency Control to 35Hz, and then adjust the Boost Control to your preference. For vented enclosures, set the Frequency Control to 10Hz below the port tuning, then adjust the Boost control to your preference.

Remote Bass Control

The mono amplifier comes with remote bass control. This allows for increasing or decreasing bass independent of the head unit's tone controls. The benefit is total control over just the bass output. The tuning is right at the driver’s fingertips.
