The RF connector is the primary RF interface to the antenna. The RF

The power connector is the interface for the primary 13.8V power source
and the external speaker. The primary power source can be the vehicle
battery or a mains-fed DC power supply. There are different power
connectors for the >25W and 25W radios.
Important
The speaker load configuration is balanced; the speaker
output lines must not be connected to ground. Connecting
a speaker output line to ground will cause audio power
amplifier shutdown
