Amplifier with RCAinput jacksCar stereo with RCAoutput jacks
RCAinput
Connecting wires with RCApin plugs(sold separately).
RCAinput jack A, B
Special red battery wire [RD-223] (sold separately). After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery.Ground wire (black) [RD-223](sold separately). Connect to metal body or chassis.
Blue [RD-223] (sold separately). Connect the male terminal of this wire to the blue wire of the car stereo (SYSTEM REMOTE CONTROL). The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch.
External Output For details on how to connect to RCA input jacks Aand B, see the OConnecting the Speakers and Input wires� section. If only one input plug is used, do not con- nect anything to RCAinput jack B.
