Step By Step Installation
NOTE:
Connect all input, power and speaker connections to amplifier
before mounting the amplifier in its final location .
Determine the location for the amplifier . Refer to the
1 .
Choosing
Mounting Locations
section of this manual for detailed informa-
tion .
Decide on the system configuration for your amplifier . For system
2 .
suggestions, refer to the
Speaker Connections
section of this
manual .
Run all the wires from the amplifier location to the speakers,
3 .
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 .
Remove end caps before mounting the amplifier (see figure 11,
4 .
previous page) .
Pre-drill amplifier mounting holes . Be sure to “think before you
5 .
drill” . Gas tanks, fuel lines, mechanical/electrical systems and/or
other obstructions may be hidden beneath mounting location .
For best results use a marking pen to mark the mounting holes
and pre-drill these holes with a standard 1/8” drill bit .
Mount the amplifier . Make sure the amplifier is mounted on a
6 .
flat surface . If this is not possible, do not over tighten the screws
so that the chassis of the amplifier is twisted or bent .
turn the vehicle’s key switch to the off position .
7 .
Disconnect the vehicle’s battery ground terminal .
8 .
Connect power wires to the amplifier (ground first, then 12 V(+)
9 .
and ReM) . Power wire must be fused near the battery . Be sure to
remove the fuse from the fuse holder at this time .
Connect the RCA and speaker wires to the amplifier . Check
10 .
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 .
Reconnect the ground terminal to the battery after power,
11 .
speaker, and RCA connections are completed .
set crossovers . Refer to the
12 .
Internal Crossover Configuration
sec-
tion of this manual for detailed instructions .
set gain control to a low level before turning on the amplifier .
13 .
Adjust gain control as needed after the system is playing . (see
adjusting the sound of the system)
once satisfied that all connections and settings are correct, install
14 .
the fuse located near the vehicle’s battery and proceed to the
Testing the System
section of this manual .
After all connections and adjustments are made, install end caps
15 .
if they are to be used .
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 .
