AMPLIFIER INSTALLATION
Choosing Mounting Locations
The location of your amplifier will depend on several important issues. Due to the low pro-
file size of the Orion 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
mounting possible. When mounting your amplifier under a seat or similar area, keep a min-
imum of 1" of clearance around the amplifier for adequate cooling.
Trunk Compartment
Mounting your amplifier in the trunk provides excellent performance as long as you do not
restrict the airflow around the heatsink of the amplifier. For optimal results, mount the
amplifier with as much clearance as possible. This type of mounting will yield the best cool-
ing due to the convection effect of the amplifier chassis.
General Precautions and Installation Tips
WARNING!
Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic
lines, vacuum lines, or electrical wiring when working on your vehicle.
Disconnect the vehicle's ground wire at the battery before making or breaking connections
to the audio system's power supply terminals.
Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in
damage or injury, particularly in the event of an accident. An unmounted amplifier becomes
a dangerous projectile in the event of a crash. Never mount the amplifier where it might
get wet. Mount the amplifier so the wire connections will not be pulled. Route the wires
where they will not be scraped, pinched or damaged in any fashion.
The +12V power supply wire must be fused as close as possible to the battery terminal, ide-
ally within 18". Use the recommended fuse size or circuit breaker listed in the
Power
Connections
section of this manual.
If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with
the same size ATC / MAXI type fuse that came with the amplifier. If you are not sure as to the
correct value, refer to the
Power Connections
section of this manual for details. Using a high-
er current fuse may result in damage to the amplifier that is not covered under warranty.
NOTE:
Make sure all the equipment in the system is turned off when making or break-
ing connections to the input RCA's or speaker terminals. Turn on the system and
slowly turn up the volume control only after double checking all wire connections.
