INTRODUCTION
Dear Cerwin-Vega Mobile Customer,
Thank you for making Cerwin-Vega Mobile your choice for high performance car audio products. At
Cerwin-Vega Mobile, our goal is to produce products of unsurpassed quality. We believe you will not
nd a better value anywhere in the mobile audio environment.
To ensure that your new Cerwin-Vega Mobile amplier provides years of enjoyment, you should
consider having it installed by a professionally trained technician. They have the knowledge to make
your new amplier perform its very best.
WARNING: Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent
hearing loss. Cerwin-Vega Mobile ampliers can exceed that level so please exercise restraint when
listening and enjoying your new amplier.
GENERAL PRECAUTIONS
• This unit is designed for negative ground 12V DC operation only.
• Total system impedance must not be less than 2 ohms.
• Avoid installing the unit where:
- It would be subject to high temperatures, such as from direct sunlight or hot air from the heater.
- It would be exposed to rain or moisture.
- It would be subject to dust or dirt.
• Do not cover the unit with carpet or wires.
• Do not use the unit with a weak auto battery. Optimum performance depends on a normal battery
supply voltage.
• For safety reasons, keep the volume of your car audio system moderate while driving your vehicle
so that you can still hear normal trafc sounds outside your car.
MOUNTING PRECAUTIONS
Although Cerwin-Vega Mobile ampliers incorporate heat sinks and protection circuits, mounting
the amplier in a tight space without any air movement can still damage internal circuitry over time.
Choose a location that provides adequate ventilation around the amplier. For easy system set-up,
mount the amplier so the side panel controls will be accessible after installation. In addition, ob-
serve the following precautions:
1. For the most efcient cooling, mount the amplier so that air runs along the length of the ns
rather than across them. Remember, any moving air across the amplier will reduce heat.
2. Mount the amplier on a solid surface. Avoid mounting to subwoofer enclosures or areas prone to
vibration. Do not install the amplier on plastic or other combustible materials.
3. Prior to mounting the amplier, make sure not to cut or drill into the fuel tank, fuel lines, brake
lines (under chassis) or electrical wiring.
WIRING PRECAUTIONS
1. Before installation, make sure the source unit power switch is in the OFF position.
2. Disconnect the negative (-) lead of the battery before making any power connections.
3. When making connections, be sure that each one is clean and secure. Insulate all of your connec-
tions. Failure to do so may damage your equipment.
4. A secure clean ground connection is critical to the performance of your amplier. Connect the
ground directly to the car chassis to minimize resistance and avoid any noise problems.
5. Add an external fuse on the amplier’s positive (+) power lead and connect it as close as possible
to the vehicle’s (+) battery terminal. Use a rating that equals the total current consumption at full
output of all ampliers in the system. This external fuse will protect the vehicle from short circuits
that can cause a re.
