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.
