INSTALLATION/OWNER'SMANUAL 2/1-ChannelMobilePowerAmplifier XIA4225 XIA4225INSTALLATION Preparation Please read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your DUAL amplifier is installed by a professional installer or an authorized dealer. BeforeYouStart · Disconnect negative battery terminal. Consult a qualified technician for instructions. · Avoid installing the amplifier where it would be subject to high temperatures, such as from direct sunlight, or where it would be subject to dust, dirt or excessive vibration. · Use extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring. · All amplifier installations require power, signal and speaker wires (not included). · An amplifier installation kit (sold separately) is highly recommended to facilitate the installation. Consult your dealer for recommendations. MountingLocation · Choose a mounting location for the amplifier. Suggested locations include under a seat or in the trunk. · The amplifier can be mounted horizontal (recommended) or vertical. For optimum performance, make sure to provide at least 1" of space to around all sides. Do not mount the amplifier under carpets or where airflow is restricted. · Do not install the amplifier where it may be exposed to moisture. · The optimum mounting location varies between vehicles. Remember to test all amplifier functions before completing the final mounting procedure. TYPICALMOUNTINGMETHOD 2 XIA4225INSTALLATION NOTE:Besuretofollowspecificinstructionsincludedwithyouramplifierinstallation kit(notincludedwiththisamplifier).Theinformationbelowshouldbeusedageneral guidelineonly. PowerWire(+12V) · Disconnect negative battery terminal before proceeding. Consult a qualified technician for instructions if you are unsure. · Plan wire routing before cutting any wires to length. Begin by routing the power +12V wire from the battery to the amplifier location. Use a grommet when running wires through the firewall or metal openings. Avoid running the power wire near existing vehicle wiring to prevent induced noise from entering the audio system. · Use extreme caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring. · The +12V wire MUST be fused within 18" of the battery for protection of the vehicle's electrical system. ConnectionDescriptions GroundWire(GND) · The amplifier ground wire should be as short as possible. Choose a clean unpainted section of metal or the vehicle chassis when attaching the ground connection. Be sure to clean the area of any dirt or grease. RemoteTurn-onWire(REM) · The remote turn-on wire connects to the head unit's amplifier turn-on lead or power antenna output. SpeakerWires · Choose adequate gauge speaker wire depending on your exact amplifier/speaker combination. Be sure to observe polarity when connecting. · Do not ground any speaker wires or connect any speaker wires together. IlluminiteCircuit(12VDCOutput-forDUALilluminitespeakersonly) · Use 18-gauge or larger wire for making the connections to the illuminite terminals of DUAL illuminite speakers ONLY. Be sure to observe polarity when connecting. · Do not ground any illuminite output wires or connect any illuminite wires together. InputSignal · The amplifier's input signal connects to the head unit's low level (RCA) or high level (speaker wire) outputs. · Low level input signal deliver the best performance. If unavailable, use the high level inputs - when interfacing with factory head unit for instance. CAUTION · Do not use both low and high level inputs at the same time - connect only one or the other. 3 XIA4225INSTALLATION ConnectionsandControls 1 2 3 4 5 6 7 14 13 12 11 10 9 8 1 2 3 4 5 6 7 Low Level Inputs High Level Inputs Input Level Control Crossover Frequency Crossover Mode Switch Bass Boost LED Indicator 8 9 10 11 12 13 14 Ground Connection Remote Connection +12VDC Battery Connection Main Fuses illuminite Fuse Illuminite Outputs Speaker Connections 4 XIA4225INSTALLATION TypicalWireRouting MainPowerConnections Connect +12V, GND and REM wires accordingly. A suitable fuse MUST be installed on the +12V lead within 18" of the battery for protection of the vehicle's electrical system. FuseRating When replacing fuses, make sure new fuse is the correct type and amperage. Using an incorrect fuse could damage the amplifier.

Power/ground4 gauge illuminiteoutput 18 gauge 5 XIA4225INSTALLATION OutputConnections The lighting elements of DUAL illuminite speakers provide you with a unique custom touch to your vehicle. Dual's patent pending illuminite LED system and control circuitry provides an extraordinary blue-hue illumination which allows great creative opportunities for the beginner and seasoned custom installer alike. DUAL XIA-series amplifiers provide a dedicated switched 12VDC output including independent fused protection (2 amp) specifically for use with illuminite speakers. DUAL illuminite speakers have two distinct sets of input terminals. The first is labeled audio input terminals and the second is labeled illuminite lighting inputs. The inputs are clearly marked with a label positioned directly above the terminal housing. The polarity (+ and -) indicators for each set of inputs also appear on these labels. 1. Do not connect the amplifier speaker outputs or any audio source to the illuminite lighting inputs. 2. Refer to the figures below for making the connections. Make sure to observe polarity as the illuminite circuitry will not operate when connected reverse polarity. Connect either red wire from the XIA amplifier illuminite outputs to the positive (+) illuminite input terminal and connect either black wire from the XIA amplifier illuminite outputs to the negative (-) illuminite input. Additionalilluminitewiringnotes: Several illuminite speakers can be connected to the 12VDC illuminite output at one time. Refer to the table below for the individual illuminite speaker current requirements. If you are unsure, consult a qualified professional or call DUAL technical assistance at 1-866-382-5476 for further information. illuminitecurrent requirements (perspeaker) XiNC112 - 55mA XiNC110 - 55mA XiNBP210 - 180mA XiNBP212 - 180mA XOBP12D - 130mA OUTPUT CONNECTOR (Plugs into amplifier) 6 XIA4225INSTALLATION AmplifierConnections SpeakerConnections Connect speaker wires observing polarity. The minimum impedance load is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XIA4225 can be wired for stereo, bridged or stereo/bridged simultaneous operation. TypicalStereoWiring (2ohmsminimum) 2Speakers(stereo) Subwoofer(mono) TypicalBridgedWiring (4ohmsminimum) InputSignalConnections LowLevelInput(RCA) Low level (RCA) input signal is preferred for best performance. Typical trunk-mount amplifier installations require a 17-20 foot RCA cable. Most trucks and under-seat applications require a 6-9 foot RCA cable. Using twisted pair construction RCA cables will minimize noise. HighLevelInput(SpeakerWire) High level inputs should only be used when RCA outputs are not available from the head unit. Connect the head unit speaker outputs to the high level input connector as shown below. The black wire (signal reference ground) may or may not require a connection to chassis ground - depending on your particular installation. CAUTION: Do not use both low and high level inputs at the same time - connect only one or the other. 7 XIA4225OPERATION Configuration/Setup InputlevelControl The input level control (gain) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match. CrossoverMode The crossover is used to filter out frequencies above or below a certain point. Choose LPF when using the amplifier with subwoofers, HPF when using with midrange/tweeter combinations and FULL when using with coaxial-type speakers. NOTE: Choose FULL when using the amplifier in stereo/bridged simultaneous mode. In this mode, passive crossovers are required. Failure to use the correct passive components may damage the amplifier and/or speakers. Consult a qualified professional for recommendations. CrossoverFrequencyControl This control allows precise adjustment of the crossover frequency. BassBoost This control provides additional boost @ 45Hz when used with subwoofers. Adjust this control with caution - as improper use can damage speakers! LEDIndicator The LED indicator illuminates green during normal operation (POWER) and red when the amplifier detects a fault (PROTECT). 8 XIA4225WARRANTY LimitedOneYearWarranty This warranty gives you specific legal rights.
