8. Disconnect the vehicle’s battery ground terminal.
9. Connect power wires to the amplifier (ground first, then 12 V(+)
and REM). Power wire must be fused near the battery. Be sure to
remove the fuse from the fuse holder at this time.
10. 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 amplifier.
Refer to the Signal Input and Output Level Controls and Speaker
Connections sections of this manual for correct wiring instruc-
tions.
11. Reconnect the ground terminal to the battery after power,
speaker, and RCA connections are completed.
12. Set crossovers. Refer to the Internal Crossover Configuration
section of this manual for detailed instructions.
13. Set gain control to a low level before turning on the amplifier.
Adjust gain control as needed after the system is playing.
(seeadjusting the sound of the system)
14. 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.
15. After all connections and adjustments are made, install end
caps if they are to be used.
WARNING!
Never exceed the recommended fuse size of this ampli-
fier. Failure to do so will result in the voiding of your warranty and
possible damage to the amplifier.
Step By Step Installation
NOTE:
Connect all input, power and speaker connections to ampli-
fier before mounting the amplifier in its final location.
1. Determine the location for the amplifier. Refer to the Choosing
Mounting Locations section of this manual for detailed informa-
tion.
2. Decide on the system configuration for your amplifier. For system
suggestions, refer to the Speaker Connections section of this
guide.
3. Run all the wires from the amplifier location to the speakers,
source unit, and battery. Do not connect the battery at this time.
Be sure to run RCA’s and power and speaker wires away from
factory electrical wires and system as they pose a great potential
for induced system noise.
4. Remove end caps before mounting the amplifier (see figure 11,
previous page).
5. 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 1/8” drill bit.
6. 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.
7. Turn the vehicle’s key switch to the off position.
