Tri-mode

For Tri-mode wiring the high frequency speakers should be run in stereo and use a passive in
line crossover (capacitor) with each to remove the low frequency . The mono low frequency
speaker would be connected in the bridge mode to the two stereo channels with a in line pas-
sive crossover (inductor) to remove the high frequencies . The high frequency speakers should
be no less than 2 ohms and the low frequency speaker should be no less than 4 ohms .

Bridging

For bridging into a single speaker load, the Orion Cobalt CO300 .2 and CO600 .2 has the ability
to bridge the front or rear channels together . The impedance of the speaker must not be less
than 4Ω

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 .
