Mounting Your Razor
any wood, metal, or carpeted surface. The heatsink can be mounted directly to the chassis of the car, or isolated
for best performance. It needs proper ventilation, so avoid mounting the amp under seats, in the engine bay, or
any other area that moisture might accumulate. Be sure the mounting screws do not penetrate the fuel tank,
vibrations can cause damage.
Warning
Power Acoustik highly recommends that an in-line fuse or circuit breaker be installed within 18” of the battery.
Although your Razor amplifier has adequate internal protection, it is possible a damaged wire between
the component and the battery may result in a fire. The in-line fuse or circuit breaker should be installed in a
location that is easy to access, and all wiring should be routed safely, following the below suggestions:
- Avoid placing wires near hot or moving objects
- Always use wire grommets when routing wire through the firewall or any other metal surfaces
- Avoid the potential for damaged wires by routing all wires away from moving hinges, seats, brake & gas
pedals, hood and trunk hinges, etc.
Power Connections
It is important to have good quality power and ground connections. Remember, to complete an electrical circuit,
the ground connection is just as important as the positive power connection. Before any power connections are
made, disconnect the ground cable of the battery. Use 8 gauge or larger automotive grade wire if the distance
from the battery to the amp is excessive. Avoid sharp or rough edges as a safeguard against short circuiting and
potential fire hazards.
GND = Connect the proper gauge ground wire to the amplifier GND terminal. Locate the position on the chassis
of the car where the amplifier will be grounded. Use solder or a crimped ring terminal to connect the ground
wire. Pre-drill the prepped chassis to bolt the ground ring terminal with a nut, bolt, and lock washer. Insulate the
metal and the connector with paint or silicone to prevent rust and oxidation. Silicone also works great to prevent
nuts and bolts from working loose in harsh environments of an automobile. Upon completion of the ground
connection, grab the wire and connector to confirm the connection is solid. To prevent engine noise, it is
recommended to ground the head unit and other electronic audio devices to the same location.
REM = Connect the remote wire (power antenna output) from the head unit to the REM terminal. If the head unit
is not equipped with a remote/antenna output, locate a wire that is controlled by the accessory position of the
key. It is important to have the amplifier turn off with the radio or key. If the amplifier remains on, the battery will
drain.
12V = Connect the proper gauge power wire to the B+ terminal. Trace the power wire through the car to the
in-line fuse or circuit breaker that is no more than 18” from the battery. Remember, the in-line fuse or circuit
breaker protects the car in the event of short circuit. Connect the in-line fuse or circuit breaker to the battery, but
do not install the fuse or activate the circuit breaker yet.

High Level input connections
The high level inputs are for use with speaker level wiring. Most factory source
units do not have RCA outputs. Use this connection if your source unit does not
have RCA outputs. CAUTION: Never use the high and low level inputs at the
same time!

Razor Pre-Amp Features
1. Remote Level Control Connection
Connect the remote level control to this
terminal. The remote level control allows
adjustment of the subwoofer level from a
remote location in the vehicle.
2. Low Pass Crossover
Adjust the frequency setting of the low pass
crossover. The frequency range is
35Hz-250Hz. Frequencies higher than the
setting will be filtered out of the audio signal.
3. Subsonic Crossover
Adjust the frequency setting of the subsonic
crossover. The frequency range is
10Hz-50Hz. Frequencies lower than the
setting will be filtered out of the audio signal.
4. Power & Protection Indicator LED
When the amplifier is on and in proper
working condition, the green LED will
illuminate. Refer to the Troubleshooting
Guide for possible solutions if the amplifer
will not power on.If the amplifier activates its
protection mode, the red LED will illuminate.
Refer to the Troubleshooting Guide for
possible solutions if the amplifier activates
its protection mode.
5. Level Sensitivity
Adjust the amplifers pre-amp sensitivity
level. The minimum sensitivity level is
250mv, while the maximum level is 6V.
6. RCA Audio Input Connection
Using high quality shielded stereo RCA
cables, connect the source signal to the
amplifier RCA inputs.
7. High Level Input
Connect the speaker outputs from the head
unit tot he high level input if RCA outputs are
not available. NEVER use high level and
RCA inputs at the same time.
8. Bass Boost
Adjust the amplifiers 45Hz Bass Boost level
up to 12dB.
9. Crossover Selection Switch
Choose an 80Hz fixed frequency high pass
crossover, 80Hz fixed frequency low pass
crossover, or full range operation.

Setting the gains:
It is a fact that very few people, including professional installers, know how to set gains
correctly. Failure to do so yields higher distortion, a higher noise floor which decreases
dynamic headroom, less than optimum operating conditions for electronic equipment, and
higher failure rate for both the electronic equipment and transducers alike.
While most people set this control by ear to how loud they want their music, this is not the
intent of this control. The range is from 0.25 volts to 6 volts. The control is meant for
matching the output of the source unit’s signal voltage. For example, if you have a source
unit with low output voltage, you would probably have the control set fairly high, towards the
0.25V range. A lot of head units have 4 volts of output signal voltage which means that your
control would be set midway through the range. If you happen to have a line driver (signal
booster) that yields 6 volts or more, you will set the gain at the minimum position, towards
the 6V range.
In all of these examples, when properly level matched, the amplifier will put out full volume.
Setting the control above the proper point may cause damage to the amplifier and speakers,
and can result in poor sound quality and overall undesirable results.
Bass Boost control:
The monoblock amplifiers feature a variable Bass Boost control, centered at 45Hz. You can
adjust the amount of boost from 0dB to 18dB.

Investigate the layout of your vehicle before drilling or cutting any holes.
Take care when you are working near the gas tank, brake lines, hydrau-
lic lines, and electrical wiring. Do not use the amplifier without securly
mounting it, as the amp or vehicle may be damaged in the event of an
accident. Do not mount the amplifier where the wire connections are
unprotected or are subject to pinching or damage from other vehicle
components. The 12V power wire must be fused within 18” of the
battery. Ensure the source unit is powered off before making any wiring
connections. If you need to replace the fuses, use only the same type
and size. Using a fuse of a different type or rating may result in damage
to the amplifier or vehicle, which will not be covered under the
manufacturer’s warranty.
