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 passive cross-
over (inductor) to remove the high frequencies. The high frequency speakers should be no less
than 2 ohms and the low frequency (bridged) speaker should be no less than 4 ohms.

Bridging

For bridging into a single speaker load, the Orion Cobalt CO6004 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.

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-
