ELECTRICAL WIRING
DC Connections
Caution: The RC900 is designed for vehicles with a 12 volt
negative ground electrical system only!
Referring to the wiring diagram on this page:
1 . Connect the YELLOW wire directly to the positive
terminal of the vehicle’s battery, or to a point that has
+12 Volts available at all times . This lead maintains
the memories within the RC900 and is the main power
source for the unit .
2 . Connect the RED wire to the vehicle’s +12 V supply
via an appropriate isolating switch or circuit breaker .
This lead enables the radio to be switched ON and OFF .
Alternatively, this wire can be connected directly to the
battery’s positive terminal and the RC900 switched ON
and OFF using it’s own controls .
3 . Connect the BLACK wire to the battery’s negative terminal
or to the common negative bus in the electrical system .
NOTE: The blue wire on the wiring loom supplies 12 volts
when the RC900 is switched on and can be used to turn on
an external device, like the GME GA9800 amplifier .
Speaker Connections
When connecting the speakers, observe the correct polarity as
shown in the diagram above right . Incorrect polarity will result in a
reduction of bass response and stereo effect . The use of speakers
with an impedance of less that 4 Ohms is not recommended, as
they will cause excessive loading of the RC900’s output circuit
and may result in the radio overheating .
CAUTION: The RC900 is a four-speaker system that
requires 2 separate wires for each speaker .
A range of GME speakers is available from your local
GME retailer .
Connect all four speakers as shown in the diagram above .
Adjust the Fader control for the required front/rear balance .
