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 amplier provides years of enjoyment, you should
consider having it installed by a professionally trained technician. They have the knowledge to make
your new amplier perform its very best.
WARNING: Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent
hearing loss. Cerwin-Vega Mobile ampliers can exceed that level so please exercise restraint when
listening and enjoying your new amplier.
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 trafc sounds outside your car.
MOUNTING PRECAUTIONS
Although Cerwin-Vega Mobile ampliers incorporate heat sinks and protection circuits, mounting
the amplier in a tight space without any air movement can still damage internal circuitry over time.
Choose a location that provides adequate ventilation around the amplier. For easy system set-up,
mount the amplier so the side panel controls will be accessible after installation. In addition, ob-
serve the following precautions:
1. For the most efcient cooling, mount the amplier so that air runs along the length of the ns
rather than across them. Remember, any moving air across the amplier will reduce heat.
2. Mount the amplier on a solid surface. Avoid mounting to subwoofer enclosures or areas prone to
vibration. Do not install the amplier on plastic or other combustible materials.
3. Prior to mounting the amplier, 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 amplier. Connect the
ground directly to the car chassis to minimize resistance and avoid any noise problems.
5. Add an external fuse on the amplier’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 ampliers in the system. This external fuse will protect the vehicle from short circuits
that can cause a re.
