Bridging
For bridging into a single speaker load, the Orion Cobalt CO500 . and CO800 . have the ability
to be bridged with another amplifier of the same model . To do this you must set the PHASE
switch on the (slave) amp, move the phase switch from 0 to 80, exactly opposite of the master
amp . Refer to the Phase Switch section of this guide .
Be sure to set all adjustment on both amplifiers exactly the same except for the phase switch .
The phase switch on the master amplifier should be 0 and the slave amplifier should be 80 .
For the speaker connections, connect the positive (+) speaker lead from the speaker to the posi-
tive (+) speaker terminal of the master amplifier . On the negative (-) speaker connection, take
the negative (-) speaker terminal of the master amplifier and connect it directly to the nega-
tive (-) speaker terminal of the (slave) amplifier . The remaining positive (+) speaker terminal of
the (slave) amplifier must be connected to the negative (-) speaker lead from the speaker . The
impedance of the speaker must not be less than 4 ohms
NOTE: For best results, connect both negative speaker terminals on the master amp to both
negative terminals on the slave amp using at least 2 AWG cable .

AMPLIFIER INSTALLATION
Choosing Mounting Locations
The location of your amplifier will depend on several important issues . Due to the low profile
size of the Orion Cobalt amplifiers, there are many possible installation locations that will yield
satisfactory amplifier performance . Always mount the amplifier in a place that protects the
amplifier from the elements . In addition, mount the amplifier on a stable, flat surface .
NOTE: Mounting amplifiers upside down is not recommended and may cause premature
thermal shutdown .
WARNING! Do not mount any amplifier in the engine compartment . Amplifiers are not
designed to endure the harsh environment of the exterior elements .
Passenger Compartment
If you are going to mount the amplifier in the passenger compartment, make sure you have
adequate room for ventilation . The amplifiers have been designed to make under-seat mount-
ing possible . When mounting your amplifier under a seat or similar area, keep a minimum of "
of clearance around the amplifier for adequate cooling .
