XIA SERIES INSTALLATION

PreparationPlease read entire manual before installation. Due to the technical nature ofamplifiers, it is highly recommended that your DUAL amplifier is installed by aprofessional installer or an authorized dealer.

Before You Start• 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 excessivevibration.

• Use extreme caution when drilling holes to avoid damaging fuel lines or existingvehicle 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.

Mounting Location• 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 notmount 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.

TYPICAL MOUNTING METHOD

NOTEBe sure to follow specific instructions included with your amplifier installation kit(not included with this amplifier). The information below should be used a generalguideline only.

Power Wire (+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 runningwires through the firewall or metal openings. Avoid running the power wire nearexisting vehicle wiring to prevent induced noise from entering the audio system.

• Use extreme caution when drilling holes to avoid damaging fuel lines or existingvehicle wiring.

• The +12V wire MUST be fused within 18" of the battery for optimum protection.

Ground Wire (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. Besure to clean the area of any dirt or grease.

Remote Turn-on Wire (REM)• The remote turn-on wire connects to the head unit's amplifier turn-on lead or

power antenna output. If unavailable, connect a SPST switch inline with a +12Vsource to control the amplifier on/off operation.

Speaker Wires• 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.

Iluminite Circuit (12VDC Output - for DUAL illuminite speakers only)• 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.

Input Signal • 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.

CAUTIONDo not use both low and high level inputs at the same time - connect only one or the other.

XIA SERIES INSTALLATION

Output ConnectionsThe illuminite lighting elements of DUAL XiN series speakers provide you with a uniquecustom touch to your vehicle. Dual’s patent pending illuminite bulb system and controlcircuitry provides an extraordinary Blue-Hue illumination which allows great creativeopportunities for the beginner and seasoned custom installer alike. DUAL XIA-seriesamplifiers provide a dedicated switched 12VDC output including independent fusedprotection (2 amp) specifically for use with illuminite speakers.

DUAL illumnite speakers have two distinct sets of input terminals. The first is labeledaudio input terminals and the second is labeled illuminite lighting inputs. The inputs areclearly 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 illuminitelighting inputs. Connecting the illuminite circuitry to more then 3VAC rms can causepermanent damage to the lighting elements.

2. Refer to the figures below for making the connections. Make sure to observe polarityas the illuminite circuitry will not operate when connected reverse polarity. Connect eitherred wire from the XIA amplifier to the positive (+) illuminite input terminal and connecteither black wire from the XIA amplifier to the negative (-) illuminite input.

Additional illuminite wiring notes:Several illuminite speakers can be connected to the 12VDC illuminite output of an XIAseries amplifier. Refer to the table below for the individual illuminite speaker currentrequirements. If you are unsure, consult a qualified professional or call DUAL technicalassistance at 1-866-626-7863 for further information.

Amplifier ConnectionsSpeaker ConnectionsConnect speaker wires observingpolarity. The minimum impedanceload for the XIA2340 and XIA2460is 2 ohms (stereo) and 4 ohms(bridged). Use of loads lower thanthese is not recommended andmay cause amplifier damage.The XIA2340 and XIA2460 can bewired for stereo, bridged orstereo/bridged simultaneousoperation.

NOTE: For stereo/bridgedsimultaneous operation, consult a qualified professional for further information.

Input Signal Connections

Low Level Input (RCA)Low level (RCA) input signal is preferred for best performance. Typical trunk-mountamplifier installations require a 17-20 foot RCA cable. Most trucks and under-seatapplications require a 6-9 foot RCA cable. Using twisted pair construction RCA cables willminimize noise.

High Level Input (Speaker Wire)High level inputs should only be usedwhen RCA outputs are not availablefrom the head unit. Connect the headunit speaker outputs to the high levelinput connector as shown below. Theblack wire (signal reference ground)may or may not require a connection tochassis ground - depending on yourparticular installation.

CAUTIONDo not use both low and high level outs at the same time - connect only one or the other.

XIA SERIES OPERATION

Configuration/SetupThe input level control (gain) is used to obtain the bestpossible match between the head unit audio output and theamplifier input. Begin by turning the input level control fullycounter clockwise. Next, turn up the head unit volumecontrol around 3/4 of the way up. Adjust the input levelcontrol clockwise until audible distortion is heard, thenslightly counter clockwise to provide the best match.

The crossover is used to filter out frequencies above orbelow a certain point. Choose LP when using the amplifierwith subwoofers, HP when using with midrange/tweetercombinations and FULL when using with coaxial-typespeakers.

NOTE Choose FULL when using the amplifier instereo/bridged simultaneous mode. In this mode, passivecrossovers are required. Failure to use the correct passivecomponents may damage the amplifier and/or speakers.Consult a qualified professional for recommendations.

This control allows precise adjustment of the crossoverfrequency.

This control provides additional boost @ 45Hz when usedwith subwoofers. Adjust this control with caution - asimproper use can damage speakers!

The LED indicator illuminates green during normaloperation (POWER) and red when the amplifier detects afault (PROTECT).
