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. 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!!!
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.
NOTE
In many cases a motorcycle or UTV will have the battery in a location that is idea for a grounding point. At the same time grounding to the body or frame could be problematic. Do to the relatively small size of the vehicle there is no disadvantage to grounding at the battery .

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.
Warning
Take extra care when using CCA (Copper Clad Aluminum) or pure aluminum wire to insure the connections as clean and tight. Do to aluminums highly reactive nature these connections can fail without the typical "Green" or tarnished look you would expect with copper. Aluminum also has a greater rate of expansion do to heat and care must be taken to insure that the connection is not over tightened. This can result in the failure of the power or ground connector and possibly the circuit board.

Input Section
This XDi amplifier in equipped with a Balanced Input Stage that is compatible with any analog source including Balanced and Unbalanced RCA, Common ground speaker level output or BTL (Bridged Tied Load) outputs common on many OEM headunits. The speaker level input plug included with this amplifier are intended to be used with speaker level outputs and include a divider network to reduce the level of the OEM system. If you are integrating into an OEM systems
balanced or common ground line level signal you should
not use these Pigtails. In this case it is recommended that you use an appropriate RCA cable with 1 set of ends removed as inputs for the amplifier.

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 gains most often need to be used to compensate for these

Remote Status Display
The
MOTO 600.4
is equipped with a Remote Status Display LED that can be mounted in a visible location near the amplifier. By simply plugging in the Status LED you will have a visible indicator that matches the function of the
Power/Protect light on the amplifier. You can use this to determine if the amplifier is on or off or if the amp is in protection and, if so, what protection fault code is displayed.
The Remote Status Display comes with approximately
18” of wire however this can easily be extended to almost any practical length.

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.
2Ω Stereo/4Ω 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.
4Ω 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.

AUTO SENSE
The MOTO 600.4
uses a BTLD (Bridge Tied Load) Auto Detect
Turn-on circuit that offers a significant improvement in reliability over previous designs. Instead of relaying on the music to supply enough signal to turn the amplifier on. Robert Zeff’s design detects the IC (chip) used in the vast majority of stock head units and amplifiers.
It is important to note the Auto Sense will not always work. Do to the hundreds (or thousands) of different OEM system configurations, no single solution can be 100% successful. If your system does not reliably switch on and off, look for an alternative turn on source. It is possible to spend many hours trouble shooting an Auto Sense problem. This is time that could be spend enjoying your new audio system.
