loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for
your system.
Low-Pass Crossover
The low-pass crossover is active with a 2nd order (12dB per octave) slope. The low-pass crossover
is continuously variable from 50Hz to 500Hz.
Remote Bass Operation
The remote bass port provides easy remote access to the internal bass gain structure of the
power amplifier. The bass gain is centered at 44Hz. The RGC-2 plugs into the amplifier via the
1/8" mini jack plug. The RGC-2 can be installed in the front of the vehicle to control the ampli-
fier bass gain level. The RGC-2 can be used as a bass level control when used on an amplifier
dedicated to subwoofers.
AMPLIFIER WIRING
Power Connections for the Orion Cobalt CO500.1 and CO800.1
● Orion Cobalt CO500.1 Fuse Size: 2 x 20 AMP ATC / CO800.1 Fuse Size: 2 x 30 AMP ATC
● Power connections accept up to 4 AWG wire.
● 4 AWG power and ground wire recommended for optimal performance.
● Connect 12V+ to the battery through 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 pro-
vides +12V power to turn-on the amplifier.
● Add extra ground wire between the negative terminal of the battery and the chassis.
Speaker Wiring Diagram CO500.1/CO800.1
The Orion Cobalt CO500.1 and CO800.1 amplifiers offer two positive and two negative output
terminals for ease of connecting the speakers to the amplifier. Since these are mono amplifiers, the
speaker connectors are paralleled internally. Each amplifier is stable to 2Ω.
