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.
