General Precautions

• This symbol indicates that you have to pay attention to these

instructions. Disregarding them might cause accidental harms

or damage your amplifier.

• Before installing the amplifier, make sure you carefully read and

understand all instructions.

• The vehicle electric system must have 12 VDC voltage with negative

to ground. Make sure your car has it in order to avoid any damages to your

amplifier and to the vehicle.

• Pre-plan the configuration of your new amplifier and the best wiring routes to ease installation.

• Always wear protective eyewear when using tools that may generate splinters.

• During installation, keep the amplifier in its packing as long as possible; this will protect it

from damages.

• Secure all auxiliary devices you built to install the components to the vehicle structure

through brackets, screws, nuts and bolts; this insures stability and safety while driving.

• The amplifier detachment while driving can damage the people in the vehicle and other cars.

Secure the amplifier at best, paying utmost attention if installation is inside the passenger’s

compartment. Use extra fixing systems if installation occurs inside the engine compartment.

• Before installing the amplifier, turn off the source and all other electronic devices in the

audio system for preventing any damages.

• Make sure the location you chose for the components does not affect the correct

functioning of the vehicle mechanic and electric devices.

• Do not run the cables or install the amplifier next to electronic gearcases.

• Use extreme caution when cutting or drilling the car plate, checking there are no electrical

wiring or structural element underneath.

• Before connecting the power cable to the amplifier, disconnect the negative lead ( - ) from

the car battery.

• Make sure power cable is not short circuited during installation and connection.

• Power cable must have mechanically resistant and self-extinguishing insulation.

Its section has to comply with what is suggested in this manual. Avoid to run it over or

through sharp edges or close to moving mechanical devices. Make sure it is well fixed all

along its length. Block positive and negative cables just close to the amplifier respective

power supply terminal blocks through a clamping screw.

• Use rubber grommets to protect the wire if it runs in a hole of the plate or proper materials

if it is close to heat-generating parts.

• To ground the device ( - ) in the right way, use a screw in the vehicle chassis; scrape all

paint or grease from the metal if necessary, checking with a tester that there is continuity

between the battery negative terminal ( - ) and the fixing point. If possible, connect all

components to the same ground point; this solution rejects most noise.

• Route all signal cables close together and away from power cables.

• Never run cables outside the vehicle; you would not be protected against wear and in

case of accidents.

• When installing speakers and the cables that connect them, make sure that non-insulated

parts never touch the vehicle cutting parts. If they do, the amplifier protection is activated.

• To prevent all problems, use very good quality cables, connectors and accessories,

choosing them in CONNECTION Audison catalogue.

• When installation is over, and before plugging the main power supply fuse, check

the system wiring and make sure all connections were done in the right way.

• Power amplifiers put an increased load on the battery and on its charging system.

We recommend checking your alternator and battery condition to ensure they can handle

the increased consumption. Standard electrical systems which are in good condition should

be able to stand this extra load without problems but we recommend the use of an energy

storage capacitor and/or a battery for high level audio systems.

• Put a fuse and its insulated fuse holder 40 cm max. far from the battery positive terminal;

connect one end of the power cable to it after connecting the other end to the amplifier.

The fuse value must be 50% higher than the amplifier built-in one. In case the cable

supplies several amplifiers, the fuse value will have to be 50% higher than the sum of the

values of all other fuses in the amplifiers.

• There must be good air circulation where the amplifier is installed; this area must not be

affected by humidity, rain, external deposits or parts coming from the vehicle mechanical

devices. Don’t cover ducts for forced cooling.

• Install the amplifier in the vehicle parts where temperature is between 0°C (32°F) and

55°C (131°F).

WARNING. When working in demanding conditions, the amplifier can reach temperatures

of around 80 – 90°C (176÷194°F). Make sure it is not dangerously hot before touching it.

• Periodically clean the amplifier without using aggressive solvents that might damage it.

Dampen a piece of cloth with water and soap, wring it and clean the amplifier. Then use a

piece of cloth dampened with water only; eventually clean the amplifier with a dry piece of

cloth.

• Remove dust and solid deposits from the ducts where air goes in and out. Don’t use

compressed air on the grilles without removing them, since it would push solid parts in the

amplifiers. If necessary, please contact a specialised service centre for internal cleaning.

Air ducts obstruction makes the amplifier go in safety.
