Bridging

For bridging into a single speaker load, the Orion Cobalt CO500.1 and CO800.1 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 180, 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 180.. 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 12 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 1" of clearance around the amplifier for adequate cooling..
