Infinity Kappa Class D 4-Channel Car Amplifier

KappaFour
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.

  • This my first experience with Infinity amps. So far i like what i see and hear. I have this powering my front stage of 6.5 CDT components and image tweets and a Memphis 10" sub. The Cdts love power and the Kappa four provides it. The Memphis sub sounds great. I replaced two amps with the Kappa four and my system hasn't sounded better. The Kappa four is simple to install with its small footprint, and adjusting is easy.

  • This Infinity amp was a pretty penny -- it was worth it though. It’s slim and can fit into tight spaces, but despite that it doesn’t get hot easily. I have it playing on an entire 6-hour drive, played at high levels but it didn’t have any issues whatsoever. I have it hooked to my Kappa 62ix speakers and it sounds amazing!

  • This amp is one of the best purchases I’ve ever done. Very powerful despite its small design. Brought this to power up my 6.5” speakers.
