Infinity KAPPA ONE K Mono Channel Amplifier 1000W RMS x1 @ 2 Ohm: Gives You Power to Shape Your Car Audio Experience in New Ways

Kappa mono and full-range, multi-channel amplifiers deliver the efficiency and power you expect from Class D amplifiers—and the performance you expect from Infinity. The comprehensive all new E.A.R.L terminal and power adapter (5-channel & mono block) enables easy installation and optimized performance. For the 5-channel and mono amplifier models, the remote bass control allows the user to increase and decrease bass output independent of head unit tone controls. The industrial design not only provides an elegant look, but also enhances power dissipation to ensure long term reliability. Kappa amplifiers give you power to shape your car audio experience in new ways.

Infinity KAPPAONEK Features:

Class D Design

Every Kappa amplifier, including the full-range models, features 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 on-board circuitry to protect from shorts, temperature, overvoltage and undervoltage. 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 newly introduced E.A.R.L terminal for better grounding. For 5-channel and mono amplifiers, 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 anodized aluminum and screwdriver access concealed by a magnetically attached panel, Infinity Kappa amplifiers have a clean, streamlined industrial design.

Full-Range Line Outputs

The full-range Kappa amplifiers (Kappa two, Kappa four and Kappa five) include full-range line outputs. This allows the audio signal to be routed to additional amplifiers or self-powered subwoofer solutions, increasing your system configuration options.
