Installation, R T S L I S T | Infinity 54a 4-Ch instruction

I N S T A L L A T I O N

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.

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.
