Power Connections
It is crucial 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 exact 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 controlled by the key’s accessory position. It is crucial 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 vehicle 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.
Power Connection. 
Hi-Level Input Connections
The hi-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. The amplifier will automatically turn off and on using
hi-level inputs, no need for remote wire input.
CAUTION: Never use the hi and low-level inputs at the same time! 
Output Wiring Configurations
RAZOR PreAmp Features
-
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. -
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. -
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. -
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 amplifier 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. -
Level Sensitivity
Adjust the amplifier’s preamp sensitivity level. The minimum sensitivity level is 250mv, while the maximum level is 6V -
RCA Audio Input Connection
Using high-quality shielded stereo RCA cables, connect the source signal to the amplifier RCA inputs. -
Hi-Level Input
Connect the speaker outputs from the head unit to the hi-level input if RCA outputs are not available. NEVER use hi-level and RCA inputs at the same time. -
Bass Boost
Adjust the amplifier’s 45Hz Bass Boost level up to 12dB.
Mounting Your RAZOR
Choosing the best mounting location for your RAZOR amplifier is crucial. The amplifier should be mounted to any wood, metal, or carpeted surface. The heat- sink can be mounted directly to the chassis of the car or isolated for best performance. II needs proper ventilation, so avoid mounting the amp under seats, engine bay, or any other area that moisture might accumulate. Be sure the mounting screws do not penetrate the fuel tank, brake lines, or other crucial fluid lines. Never mount the amplifier to a subwoofer enclosure, as excessive 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, 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: Setting the Gain:
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 a 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 reasonably high, towards the 0.25V range. Many head units have 4 volts of output signal voltage which means that your power would be set midway through the scope. 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, the amplifier will put out the total volume when properly level matched. Setting the control above the appropriate point may cause damage to the amplifier and speakers and result in poor sound quality and overall undesirable results.
Bass Boost Control:
The Mono block amplifiers feature a variable Bass Boost control, centered at
45Hz. You can adjust the amount of boost from 0dB to 18dB. 
Trouble shooting.
Warning
Investigate the layout of your vehicle before drilling or cutting any holes.
Take care when working near the gas tank, brake lines, hydraulic lines, and
electrical wiring. Please do not use the amplifier without securely 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
damage the amplifier or vehicle, which will not be covered under the
manufacturer’s warranty.
