Orion Car Audio 7005 - Manual (Page 11)

Remote Gain Operation
The remote gain port provides easy remote access to the internal gain structure of the sub-
woofer section of the Orion 7005 amplifier. The RGC-1 plugs into the amplifier via the 1/8"
mini jack plug. It can be installed in the front of the vehicle to control the amplifier gain
level, and can be used as a bass level control on the subwoofer channel of the Orion 7005.
AMPLIFIER WIRING
Power Connections
● Fuse Size: 70 AMP MAXI
● Minimum eight-gauge power and ground cable is recommended for acceptable
performance.
● Fuse power wire prior to wire passing through panels or near sharp edges and less
than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Add extra ground wire (minimum eight-gauge) 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 helps espe-
cially in newer vehicles, where the current delivery of the factory electrical system
was designed only to accommodate electronics supplied by the auto manufacturer.

Five Channel Stereo Configuration
● Front, rear, and subwoofer channels' lowest recommended impedance is 2W stereo.
● Crossover mode, output, and gain configurations are independently adjustable
between the front, rear, and subwoofer channels.
● Two-channel or four-channel input can be used for this configuration. For source
unit fading, use the four-channel input mode.
● The subwoofer channel can use internal or external input. If the source unit has a
separate subwoofer out, use the external input configuration.
● Front, rear, and subwoofer outputs can be configured for high-pass, low-pass,
band-pass, or full range operation.
