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

This ARC Audio amplifier uses a Full Range Class D architecture that significantly improves efficiently, lowers heat production 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.

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. 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 Amplifiers are designed for easy installation in your motorcycle, car or UTV. 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 structure. Pay close attention to what is behind the panels. 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 motorcyc or automotive electrical and mechanical systems contact a professional installer.

Paying a qualified installer is almost always cheaper then paying a dealership for an avoidable repair.

Locating the Amplifier

The amplifiers must be securely mounted to a solid surface. Please select a dry location only. Do not mount the amplifier to any area that may have excessive vibration, and position the amplifier in an area that receives sufficient airflow for proper heat dissipation.

This amplifier is not fully waterproof. Please find a dry and protected location to mount it

Supplying Enough Power

The Laws of Nature

Your amplifier Does NOT make power. It converts power, or current, from your 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!!!

A quality ground is necessary for the amplifier to function propery. In some applications, you may be able to ground directly to the chassis. In others, like a motorcycle or side by side, the ground wire should connect directly to the battery. It is important to note, you should 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.

1

TOP

Running the Cables

Carefully run the power and signal cables through the passenger compartment of the vehicle. Running power down one side and signal down the other is the preferred method. If this isn’t possible, keep them separated as much as possible.

When running through any metal, always use a rubber grommet to prevent the power wire from shorting and to reduce the risk of fire. A 4 gauge or larger wire should be used for power and ground connections. ALWAYS install a fuse on the power wire within 18 inches of the battery for safety.

Recommendations for all Class D amplifiers

Class D amplifiers by the nature of there design emit a certain amount of RF (Radio Frequency) radiation. While we have optimized the design to reduce this to a minimum level there are still steps you can take to eliminate any unwanted FM radio interference. The tips below apply to any class D amplifier.

Always mount the amplifier as far from the antenna as the installation will allow. At the same time you will want to keep it away from the radio or any other electronics that may prove to be sensitive to FR radiation.

Make the ground wire as short as possible. Think of the ground like it is an antenna. Short antennas do not work as well.

Use twisted pair wires as much as possible. If you can manage it all the speaker wire and input cable weather by RCA or speaker level should be twisted. If you do not have twisted pair wire you may be able to twist it yourself.

If you encounter a problem with FM interference you can try turning the amplifier 90 degrees or changing its location completely. RF radiation can be very directional.

Gain

Because of the wide range of head unit output configurations all ARC Audio amplifiers have an adjustable input sensitivity or “Gain”. The gain is not a volume or a power limiting control like a throttle. It makes the amp more sensitive to input from the stereo. With the gain up the amp will reach full output at a lower volume setting on the deck. At higher gain settings the amp also becomes more sensitive to noise from the car’s electrical system. Try to run the gain at the lowest setting possible for you system.

There is no correct gain setting. Because speakers require different power demands to reach the same output, the

2CH gains most often need to be used to compensate for these differences. If you tried to set all the gains at half way you would probably find the system didn’t sound very good.

Ohm Load Matching

This amplifier is equipped with a unique impedance matching system that allows you to mix a wide range of Ohm loads and still achieve full power. This can be done independently on the front and rear channels.

2 Ω Stereo/4 Ω Bridged

Any speaker or combination of speakers with a total combine Ohm load between 2 and 4 Ohms (not lower then 2 Ohms) must use position. Bridged loads down to 4 Ohm must use this position. The amplifier will make full power at 2 Ohms

Stereo (4 Ohms bridged). Note: you can use any Ohm load above 2 Ohms in this position however power output will drop as the impedance increases.

4 Ω Stereo

Any speaker or combination of speakers with a total combine Ohm load over 4 Ohms can use position. The amplifier will make full power at 4 Ohms stereo (8 Ohms bridged).

TURN ON

WARNING: This amplifier will not operate and could be damaged if used in the wrong configuration. At no time can it be operated below 2 Ohms stereo or 4 Ohms bridged.

Speaker outputs

This amplifier is a multi channel amplifier design. Meaning it has more than one channel of speaker outputs. It is equipped with a removable plug style terminal for speaker wire connections up to 14 AWG. Make this connection carefully and neatly. Strip your wire back 5/16” and twist the exposed leads and insert them into the block terminal while being careful that there is no loose or frayed strands of wire.

Tighten the standard head screw down on the terminal until the wire is tightly secured in place. If the wires ever come in contact with each other the amplifier will go into protection.

Know your total ohm load before you make any connections.

Installation Instructions

Below is a very abbreviated set of installation instructions. This is not meant as a step by step procedure but is intended to give you a general idea of what is involved and which steps come first. Every installation will be different and may require reordering of these steps. NEVER install the fuse at the battery or connect the negative battery cable until all your connections are final.

Before you start, disconnect the negative cable from any batteries in the car. Tape up the end so it is isolated from the battery.

Run an appropriate gauge wire from the battery to the amplifier (8 AWG Min.). Plan this part of the installation carefully. This cable will carry very high current. If it should short to the body and it is not properly fused it could catch fire. You DID use a grommet or loom when you ran it through any metal bulkheads, didn’t you?

Connect the power wire to the battery using a fuse that does not exceed the fuse rating or the amplifier connected. Don’t install the fuse yet. Wait until the end. Locate the fuse as close as possible to the battery. If the fuse is further than 18 inches (wire length) from the battery, you should reevaluate the wire and fuse placement.

Find a close clear metal area to the amp for a ground. In many cases the best ground location is the batter itself.

Sand, grind or scrape all paint and undercoating from the body and screw the ground securely in place. A nut, bolt and lock washer is advisable here.

It is advisable to test the ground with an Ohmmeter between the ground cable and the negative battery cable to insure a good low resistance connection. Some modern alloys do not offer the best ground. If you believe this is the case, consult with the vehicle’s manufacturer.

Run the speaker wire to the speakers. It is advised that you leave some extra wire at this point. You can “clean it up” later.

If you haven’t already done so, mount the amp now.

Connect the power and ground to the amplifier.

Only after this step should you install the fuse at the battery.

Connect the remote wire or select the auto sense feature if compatable. Now is a good time to turn on the amp for the first time. Make sure it turns on properly and does not go into protection.

Connect the speaker wires to the amp and speakers (make sure the amp is off first). Make sure the polarity (+ and -) is correct.

Connect the RCA signal wires to the amp.

Double check the amplifier controls at this time. Make sure everything is set correctly for your system.

Now you’re ready to play it for the first time. It is best to leave the gain all the way down at first. Start with the head unit volume low and work your way up.

Now you can tune the amp. Take your time and make only one adjustment at a time. It may take some time to get the system fully adjusted. During this time the amp is drawing current from the battery. You should check the battery voltage from time to time and re-charge it if it gets low. That’s it. You’re done. Now have fun.

ave fun.
