Mounting Your Razor

Choosing the best mounting location for your new Razor amplifier is crucial. The amplifier should be mounted to 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 the seats, in the engine bay, or in any other area where moisture might accumulate. Be sure the mounting screws do not penetrate the fuel tank, brake lines, or any 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:

• 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 the 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 in 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 turned 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 a 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 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.
5. Level Sensitivity Adjust the amplifier’s 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 to the high-level input if RCA outputs are unavailable. NEVER use high-level and RCA inputs at the same time.
8. Bass Boost Adjust the amplifier 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 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 to match the output of the source unit’s signal voltage. For example, if you have a source unit with low output voltage, the control would probably be 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 18 dB.

Troubleshooting.

Warning

Investigate the layout of your vehicle before drilling or cutting any holes. Take care when you are working near the gas tank, brake lines, hydraulic lines, and electrical wiring. 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 result in damage to the amplifier or vehicle, which will not be covered under the manufacturer’s warranty.
