6 – Infinity Kappa 54a Power Amplifier
The Kappa 54a is easy to install. For optimum
performance, we recommend using high-quality, twisted-
pair shielded RCA audio cables and 14-gauge or larger
speaker wire. Also, you’ll need a minimum of 12-gauge
stranded copper wire (e.g., red and black jackets) for the
power connections. Use 18-gauge (e.g., blue jacket) wire for
remote turn-on.
Depending on your total system plan, allow for adequate
time and the possibility of overnight storage of your vehicle,
since it may take more than one day to complete the
installation.

The Kappa 54a can be mounted in virtually any location
inside the vehicle. However, make sure to keep the
amplifier away from heater vents or ducts.

W IRING THE AMPLIFIER...
Refer to Figure 7 (below) for details of the Kappa 54a’s front
and rear panel connections.
1. For power, remote, and speaker wires, strip
1
⁄4" off one
end of each jacket to reveal bare wire for insertion into
the Weco connectors.
2. Using the Weco 2-pin power connector, connect a black
wire from the nearest bare-metal chassis component to
the (–) terminal. Then, connect a red wire from the
vehicle’s +12-volt battery terminal to the (+) terminal.
