Infinity KAPPA FOUR 125W x 4 Full Range Class D Amp

Factory Reconditioned
Limit 3 per customer

Features

Infinitys new Kappa amplifiers have been engineered to deliver world-class reliable power delivery in an all new compact footprint. So, not only do Infinitys new Kappa amps sound great, but they take less space than any amplifier we have ever engineered and are smaller and easier to install than the amps available from the majority of our competitors.

Class D/DirectFET Technology: The Infinity Kappa Four features high-power Class D circuit topology with DirectFET transistors, a design that increases power output and overall efficiency, with improved heat transfer from the transistors to the chassis.

CEA-2006 Compliance: The specifications given by Infinity for the Kappa Five comply with the CEA-2006 Amplifier Power Standard from the CEA (Consumer Electronics Association). All manufacturers who comply with the standard can display the CEA-2006 logo on their product.

4-Channel Design: This amplifier is designed to power four full-range speakers. All four channels are 2Ω stable; at 2Ω the power output is 150 watts RMS x 4. CEA-2006 compliance is maintained at 2Ω, with less than 1% THD+N. The amplifier's front and rear channels are individually bridgeable, so the Kappa Five can run 4, 3, or 2 channels. When bridged, the front and/or rear channel output is 300 watts RMS into 4Ω.

Protection Circuitry: The amp features protection circuits and will shut itself down in the following cases:

  • DC Output: DC voltage is detected on the amplifier output
  • Over/Under Voltage: Voltage at the +12V (Battery) terminal is too high or too low
  • Short Circuit: Short circuit in speaker or speaker wire
