results use a marking pen to mark the mounting holes and pre-drill these holes
with a standard 1/8" drill bit.
Step 5
Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If this
is not possible, do not over tighten the screws so that the chassis of the amplifier
is twisted or bent.
Step 6
Turn the vehicle's key switch to the off position.
Step 7
Disconnect the vehicle's battery ground terminal.
Step 8
Connect power wires to the amplifier (ground first, then 12 V(+) and REM).
Step 9
Connect the RCA and speaker wires to the amplifier. Check the quality of your
speakers and signal connections. This will determine the ultimate performance of
your Orion Cobalt amplifier. Refer to the
Signal Input and Output Level Controls
and
Speaker Connections
sections of this guide for correct wiring instructions.
Step 10 Reconnect the ground terminal to the battery after power, speaker, and RCA con-
nections are completed.
Step 11 Set crossovers. Refer to the
Internal Crossover Configuration
section of this manual
for detailed instructions.
Step 12 Once satisfied that all connections and settings are correct, install the fuse located
near the vehicle's battery and proceed to the
Testing the System
section of this
manual.
WARNING!
Never exceed the recommended fuse size of this amplifier. Failure to do so will
result in the voiding of your warranty and possible damage to the amplifier.
SET UP AND TROUBLESHOOTING
Testing the System
After you have completed the installation, you need to test the system. This will help ensure years
of trouble-free operation. Please refer to the listed steps below when testing the sound of your
Orion Cobalt system.
Step 1
Check all the wiring connections to be sure they are correct and secure.
Step 2
Turn the signal source volume control all the way down. Set any tone controls to
their flat or defeated positions. This includes the loudness control.
Step 3
Turn the level controls of the amplifier to their minimum positions.
Step 4
Turn the source unit on. Check to see if the power LED located on the connection
side of the amplifier is on. If not, please refer to the
Power Connections
and the
Troubleshooting Tips
sections of this manual for instructions.
Step 5
If using an aftermarket source unit, turn the level controls of the amplifier about
one quarter of a turn. Slowly increase the volume level of the source unit to so that
you can hear the output of the system. If no sound is heard or if the output is dis-
torted, turn the system off immediately. Refer to the
Power Connections
and the
Troubleshooting Tips
sections of this manual to solve your installation problems.
Step 6
Check to make sure the output for each channel is correct. If the active crossovers
are used, check to make sure that each output is correct from the amplifier. When
using active crossovers on midrange and tweeters, do not use crossover frequen-
cies lower than recommended. If the system is not configured properly, refer to
the
Internal Crossover Configuration
section of this manual and take corrective
action.
Step 7
If the output is clear and undistorted, continue to the
