Four-Channel Full-Range Class D Car Audio Amplifer with Built-in Electronic Crossover and Preamp Outputs. Its compact footprint is only 13" x 7-1/16" x 1-3/4", making it idea for tight installations.

Infinity's new Kappa amplifiers have been engineered to deliver world-class reliable power delivery in an all new compact footprint. So, not only do Infinity's 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. This has been accomplished using a high-power class-D amplifier circuit design which provides high output power, high overall efficiency and efficient transfer of heat from the transistors metal cases to the heat sink for the ultimate in space-saving amplifier design.

The Kappa Four features both a 12dB per octave electronic crossover and bass boost circuit, allowing you to optimize speaker performance based on enclosure type, location and subwoofer selection.

The Kappa Four features a pair of unique input selection switches eliminating the need for Y-adapters and simplify signal connections.

Differential Signal Inputs eliminate ground loops that cause engine noise and work with a variety of output configurations. Speaker-level, line-level single-ended and line-level balanced output signals from any source unit can be connected directly to the Kappa amplifiers RCA-type input connectors. High common-mode noise rejection eliminates alternator noise often present on the cars chassis and electrical noise radiated into the signal cables. In a nut shell, common mode noise rejection works by amplifying the difference between the positive and negative leads of each signal input. Since noise is present and identical on both positive and negative, its cancelled by the circuit and all that is left is the music.

Smart protection circuitry guards against short circuits in the speaker output leads, under- and over-voltage due to a weak car battery or alternator or a failed voltage regulator in the cars charging system, and protects your speakers in the event of an amplifier failure. Additionally, Kappa amps include thermal protection that never leaves you without your music. Conventional thermal protection circuits shut the amp down completely if it gets too hot. The thermal protection circuit in Kappa amps reduces the output level slightly, reducing the amount of heat generated until the amplifier reaches an optimum temperature. The amp cools itself but the music never stops.

The Kappa Four accepts up to 4 AWG power and ground cables using the included 4-gauge terminal adapters.

RCA pre-outs enable you to easily expand your sound system.
You can significantly improve your in-car sound quality by connecting extra amplifiers (and upgrading your speakers) to your headunit.

The unit of measurement for impedance or resistance. It tells you how much a device will resist the flow of current. If you take two signals of exactly the same strength and send one to a 4-ohm speaker and the other to an 8-ohm speaker, twice as much current will flow through the 4-ohm speaker. In other words, the 8-ohm speaker will require twice as much power (wattage) to play at the same volume.


The range of sounds, from bass to treble, a stereo component can reproduce. It's measured in Hertz (Hz), and a wider range is better the bass will be lower and the treble will be higher. Humans can perceive sounds from 20 to 20,000 Hz. The lowest note on a bass guitar is about 41 Hz. Most male vocalists have a range between 100 and 500 Hz. Cymbals hit at about 15,000 Hz.

A measure of how well a CD player silences background noise. Higher ratings, in decibels (dB), indicate less noise.


Amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 1% is inaudible.

The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds. When choosing an amplifier, the RMS rating is the power rating you should pay most attention to.
