potential for induced system noise .
Step 4 Pre-drill amplifier mounting holes . Be sure to "think before you drill" . Gas tanks,
fuel lines, and other obstructions have a nasty way of hiding themselves . For best
results use a marking pen to mark the mounting holes and pre-drill these holes
with a standard /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 2 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 0 reconnect the ground terminal to the battery after power, speaker, and rCA con-
nections are completed .
Step  Set crossovers . refer to the Internal Crossover Configuration section of this manual
for detailed instructions .
Step 2 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  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 input
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
