Infinity KAPPA FIVE 2300W High-Performance Multi-Channel Class D Amplifier

This handsome little black box delivers big power for your whole system and fits almost anywhere in your car. Infinity’s Kappa Five 5-channel amplifier can supply four separate speakers with 75 watts RMS each, plus a subwoofer with 350 watts RMS — good news for everyone who likes their music loud. You could also use this amp to power a pair of high-performance speakers with 200 watts RMS each, and a subwoofer with 350 watts RMS.

Terminals
The Infinity Kappa Five uses set screw terminals for the +12V power, ground, remote turn-on, and speaker outputs. The terminals are located under a magnetic cover, which can easily be pried off to access the screw heads. The screws can be tightened/loosened with a Phillips-head screwdriver (not provided).

Power/Ground
The +12V Power and Ground terminals will accept up to 4-gauge wire. It is recommended that you use a minimum of 4 AWG power wire to the battery, with an in-line 100A fuse installed no more than 18″ from the battery terminal. A 4 AWG ground wire (minimum) is also recommended, and attached to a metal area close to the amplifier.

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.

Remote Turn-On
The Remote screw terminal will accept up to 8 AWG wire. Typically, an 18 AWG turn-on lead is included in an amplifier wiring kit.

Power/Ground Adapter
If you wish to use power and ground wire larger than 4 AWG, you can use the included plug-in adapter. The adapter has posts that insert into the +12V, REM, and GND terminals and offers 1/0 AWG power and ground terminals. An 18 AWG screw terminal for the remote turn-on wire is also provided.

Speaker Outputs
The amp features set screw terminals for connecting four speakers and one subwoofer. The amplifier’s minimum speaker impedance is 2 ohms.

Line-Level Inputs
The amplifier is equipped with three pair of RCA inputs for connecting stereo RCA patch cables from the head unit to the amp.

Speaker-Level Input
The amp includes six speaker-level adapters (bare wire-to-RCA) for connecting the amp to a factory radio or aftermarket head unit. You should insert the speaker wires from the head unit into the adapters and plug the adapters into amp’s RCA inputs.

Remote Level Control
An RJ-25 modular “phone” jack is provided for connecting the Remote Level Control cable.
