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. 2 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 powerwire.lt is recommended in high power application that you upgrade your vehicles factory battery ground lead to the frame and engine grounding points to ensure the best possible circuit to allow you to receive all of the power benefits you new amplifier has to offer. To reduce the risk of noise, run all signal cable 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 make sure to use an insulated grommet to prevent the power wire from shorting when passing any cables thru a metal panel and to reduce the risk of fire. Always use the proper size power wiring when installing your new amplifier. Depending on the size of your amplifier a 4 gauge or larger wire should be used for power and ground connections. It is also advised and recommended that a fuse be installed on the power wire within 18 inches of the batter or power source for safety. 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 @ 1 KHz without clipping. Music is very dynamic. Nothing like a 1 KHz 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. 3 Input Section 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 uptheamp will reach full outputata lowervolume 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 differences. If you tried to set all the gains at half way you would probably find the system didn't sound very good. Using good judgment and listening carefully to each speaker is still the best way to tune a system. FRONT GAIN REAR GAIN Input Mode Switch All ARC Audio amplifiers include an input mode switch.This switch controls the signal being sent to the amplifier sections. Most 2-channel amplifiers can be bridged into a single channel however if the signal to the channels is not exactly the distortion will increase significantly.The mode switch solves this problem by offering 3 modes of op...
