The Ground!!!
Warning: Read this Carefully
The ground wire should be connected directly to the chassis of your vehicle. Find a clear location close to the amplifier
and remove all the paint and sound deadener. Use a #10 or larger screw to secure it. A nut, bolt and lock washer would be
better still. Never use seat belt bolts for grounding.
Remember, the ground must carry the same high current as the positive power wire.
To reduce the risk of noise, run all signal cables away from any vehicle or power supply wiring.
Supplying Enough Power
The Laws of Nature
Your amplifier Does NOT make power. It converts power, or current, from your cars electrical system and turns it into a high
power musical energy. If the amp can't get all the power it needs it will not produce its full output. Your ARC Audio ampli-
fier will produce Full output for longer then other amps on the market today. If the Voltage or Current drops too low even
our amplifiers will drop below their rated output. Make sure your vehicle charging system is in good working order. Any
Hi-Performance audio amplifier will increase the demand on your alternator and battery. If you are unsure have your
charging system tested by a professional technician.
Locating the Amplifier
The amplifiers must be securely mounted to a solid surface. Please select a dry location in the trunk or passenger compart-
ment only. Do not mount the amplifier to any area that may have excessive vibration (like the subwoofer box). Position the
amplifier in an area that receives sufficient airflow for proper heat dissipation.
Warning
We build all ARC Audio products to play at high volumes for extended periods of time. Your ears however are not
designed for high volume listening. This product can easily generate volumes that can permanently damage your
hearing. We urge you to limit your exposure to very high volume sound.
You may also find your state has laws governing the volume of an audio system in a car. Please be aware of all local and
state laws in you area.
A properly tuned and operated audio system will deliver years of enjoyment when used properly.
Installation Instructions
ARC Audio XDi Amplifiers are designed for easy installation in your vehicle. To ensure proper operation of your new
purchase, please follow the suggestions we have listed below:
Warning
Please check the suitability of the installation location before you begin. Do not cut any of the car’s structure. Pay close attention
to what is behind the panels or carpet. Often the manufacture will hide wires, computers or other electronic devices in the exact
areas you wish to install in.
If you do not have experience with automotive electrical and mechanical systems contact a professional installer. Paying a
qualified installer is almost always cheaper then paying a dealership to repair your car.
Thank you for purchasing an ARC Audio Hi-Performance Amplifier.
This ARC Audio amplifier uses a Full Range Class D architecture that significantly improves efficiently, lowers heat output
and current draw. Don’t be fooled by the small size. Class D amplifiers make more power for their size then traditional
designs making installation a breeze without compromising storage space.
