Infinity KAPPA TWO 2 Channel Amplifier 100W RMS x2 @ 4 Ohm: Delivers Big Power and Fits Almost Anywhere in Your Car

This handsome little black box delivers big power and fits almost anywhere in your car. Infinity’s Kappa Two 2-channel amplifier can supply a pair of high-performance speakers with 100 watts RMS each — good news for everyone who likes it loud and clean. You could also use this amp bridged in one-channel mode to power a subwoofer with up to 240 watts RMS. The variable high- and low-pass filter optimizes the amp’s output for your speakers or subs, increasing the efficiency of the system.

Infinity KAPPATWO Features:

E.A.R.L. Terminal

An Electrical Anti-Rotational Locking (E.A.R.L.) terminal is provided for the ground wire. The terminal is designed for 4-gauge wire and requires a large crimping tool to secure. Three screws are included to attach the terminal to your vehicle’s metal chassis.

Speaker-Level Input

The amp includes two speaker wire to RCA adapters, for connecting the amp to the speaker-level output of a factory radio or aftermarket head unit.

Protection Circuitry

The amplifier features protection circuitry for overheating, DC voltage on the audio output, over- or under-voltage (<9V or >16V), and short circuits. An LED lights red if the amp goes into protection mode.

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.

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.
