Remote Gain Operation
NOTE: Do not use the Remote Gain control when you have an expanded system installed
(see Line Ouput Configurations). The Slave amplifier(s) gain will not be controlled.
The remote gain port provides easy remote access to the internal gain structure of the HCCA
power amplifier. The RGC-1 plugs into the amplifier via the 1/8" mini jack plug. The RGC-1
can be installed in the front of the vehicle to control the amplifier gain level. The RGC-1 can
be used as a bass level control when used on an amplifier dedicated to subwoofers.
AMPLIFIER WIRING
Power Connections for the HCCA-D600
● Orion Fuse Size: 1 x 30 AMP ATC
● Power connections accept up to 0 AWG wire.
● 0/1 AWG power and ground wire recommended for optimal performance.
● Connect 12V+ to the battery through a fuse holder. This connection provides +12V
main power to the amplifier.
● Power wire must be fused no more than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Connect REM terminal to remote turn-on lead from source unit. This connection
provides +12V power to turn-on the amplifier.
● Add extra ground wire between the negative terminal of the battery and the
chassis.
NOTE: The addition of a ground wire from the battery to the chassis of the vehicle
improves the ability of the battery to supply power to the amplifier. This is recom-
mended because the current delivery of the factory electrical system was designed
only to accommodate electronics supplied by the auto manufacturer.
Speaker Connections
The Orion HCCA-600D amplifier offer two positive and two negative output terminals for
ease of connecting the speakers to the amplifier. Since this is a mono amplifier, the speak-
er connectors are paralleled internally. The amplifier is stable to 1W.
