8. ested 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 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 Input Section Because of the wide range of head unit output configurations all ARC Audio ampl
9. fuse as close as possible to the battery If the fuse is further that 18 inches wire length from the battery you should reevaluate the wire and fuse placement Find the closest clear metal area to the amp for a ground Sand grind or scrape all paint and undercoating from the body and screw the ground securely to the body 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 alloys used in modern cars do not offer the best ground If you believe this is the case consult with the vehicle 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 from the head unit to the amplifier 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 protect 10 11 12 13 14 Connect the speaker wire to the amp and speakers make sure the amp is off first Make sure the polarity and is correct Connect the RCA s 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
10. idging Bridging is a way to combine the power of 2 channels into 1 When you wire the amp bridged you have a higher voltage differential between and That means MORE POWER If you have 2 identical properly designed mono amplifiers They can not be a stereo amp that is bridged internally you can bridge them together to create 1 channel 1 Run a jumper wire between the negative a a speaker output of the 2 o amps Use the same gauge speaker wire you used to connect the speaker from amplifier 1 Normal positive output to the woofer from amplifier 2 Slave positive output to the woofer sonms When you are finished it should look like this Warning When bridging any amp or amps each channel sees half the ohm load 4 ohms bridged is the same as 2 ohms stereo 1 ohm bridged is equal to 1 2 ohm stereo Check the compatibility of you woofers and amplifier before you begin 6 Bridging Cont For bridging to work both amplifiers must be playing exactly the same signal at exactly the same output level To make this easier we have added a Slave In and Slave Out to this amp When you use the Slave In all the gain and crossovers are bypassed This eliminates all the compli cateted tuning needed to match each amp When bridging 2 amp 1 amp will act as the positive output and the other will
