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 FD Series 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.

Locating the Amplifier

The amplifiers must be securely mounted to a solid surface. Please select a dry 
location in the trunk or passenger compartment only. Do not mount the amplifier to 
any area that may have excess vibration (like the subwoofer box). Position the 
amplifier in an area that receives sufficient airflow for proper heat dissipation.

Congratulations!

Thank you for purchasing an ARC Audio Hi-Performance Amplifier.

ARC Audio amplifiers are conservatively rated and produce more power per channel 
than others in there class. Manufactured to the highest standards of quality and 
reliability to deliver years of listening enjoyment.

SOLID CONSTRUCTION for SOUND Car Audio Systems.

Setting the Gains

So you're worried that your 4 Volt output head unit will be too much for the ARC Audio's 2.5 Volt 
input stage.

Don't Be

ARC Audio Amplifiers input stage is rated to 2.5 volts RMS @ 1KHz without clipping.

Music is very dynamic. Nothing like a 1KHz test tone. It would be rare to see a peak as high as a test 
tone. Furthermore, your head unit produces its output at full volume but when you tune your system 
you always set the head unit to 70% of maximum volume.

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 amplifier 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.

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. Never use 
seatbelt 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.

Running the Cables

Carefully run the power and signal cables through the passenger compartment of the vehicle. 
Always use a rubber grommet to prevent the power wire from shorting and to reduce the risk of fire. 
An 4 gauge or larger wire should be used for power and ground connections. We recommend a fuse 
be installed on the power wire within 18 inches of the battery for safety.
