InstallationBefore you begin installation

Before you begin you need to read the manual, to havesome tools, cables and other material available. Thereis one such list of material on the following page.

Amplifier location

Important Allow air circulation around the amplifier.

2

Disconnect Battery

Before starting the instal-lation, always disconnectthe negative terminal ofthe battery.

The X-program series of amplifiers have a compactdesign that allows great flexibility in mounting. Youcan mount it under a seat or in the trunk.When you select a location, do remember that theamplifier generates a lot of heat.

Choose a location where air can circulate freelyaround the amplifier. Do not cover the amplifier withcarpets or hide behind trim panels.Do not mount the amplifier in an inverted or upsidedown position.

Check all locations and placements carefully beforemaking any cuts, drilling any holes or making anyconnections.

X-logo on amplifier cooling flange

The X-logo on the amplifier top is attached withtwo 1 mm hex. screws. The logo can be removedand twisted 90 or 180 degrees, and then screwedback in wanted position. The logo can be mountedin four different ways to match your installation.

Mounting

Fasten the amplifier to the surface using the fourseparate brackets coming with the amplifier. Thebrackets are attached to the amplifier with screwsand can be directed in two ways, see figure:

Mount the flanges this way, or this way.

Professional Tip:

If amplifier installation kits are available withdifferent size of power cable, chose the mostheavy power cable to improve sound quality andto allow more amplifiers to be installed now orlater.The amplifier power terminals accept AWG 4cables directly, so If possible buy AWG 4 = 21mm2 cable for best performance.Both the positive wire and the ground wire musthave the same size. To avoid cable fire, be surenot to oversize the main fuse value for the powerwires.

THE DC-FEEDMaximum main fuse values for different cablesizes. 6 mm2 (9 AWG) :25 A 10 mm2 (7AWG) :40 A 16 mm2 (5AWG) :60 A 21 mm2 (4AWG) :100 A 33 mm2 (2AWG) :150 A 42 mm2 (1AWG) :200 A

Power terminal ( +12V)Connect the fuse holder as close to the vehiclebattery + as possible, using AWG 4 = 21 mm2

power cable. Use a ring crimp terminal cable toconnect to battery +. Apply silicon grease to thefuse to prevent corrosion. The AWG4 cable canuse an 80 Amp fuse, if the cable is smaller, thefuse value must be lower (see table on previouspage).

Connect to a good chassis ground. The groundconnection should be clean, unpainted metal to prov-ide a good electrical connection. Use a wire brush,a scraper or a piece of an abrasive sheet to cleanthe metal. Use a lock washer or two to securecontact. Protect with silicon grease or by paintapplied afterwards.

Power Light / Protect light

The power light (green ) comes on whenthe amplifier is turned on.

The protect light ( red ) comes onwhen the amplifier shuts down fromoverheating, or a short circuit ( spea-ker failure)

Fuses

For RCA cable signal input:Connect the radio power antenna lead = remoteturn on/off from the car stereo to the amplifier remoteconnection. This turns on the amplifier wheneverthe car stereo is turned on.You can either use the built in remote cable in theRCA cable itself or use a separate cable.

Sometimes a small disturbance may enter theamplifier coming from the remote voltage , throughthe built in remote wire and into the RCA cable.Thus we recommend to use a separate remote wireand run the RCA lead separate from remote wire,power cables and speaker cables.You can insert the cable directly into the amplifierterminal. If there is no remote voltage available fromthe stereo, you must connect to the ignition keythrough the radio or any accessories fuse.

For High Level input:We recommend you to connect the remote wire asdescribed above. The amplifier will produce soft on/ soft off operation this way.In the case that there is no remote voltage availablefrom the car stereo or you want to simplify the in-stallation, the amplifier can be turned on/ turned offby the high level input voltage. This is doneautomatically when the head unit is turned on. Thereis a small disadvantage that this function gives softturn on operation but some pop sound whenswitching off.

GND REM +12V Fuse

A cable up to AWG 4 fits directly in the amplifier +12 V terminal, tighten with the hex screw.

Be sure to use a rubber grommet or a plasticinsulating tube where the cable passes the firewallor other places where it can be easily jammed.Use wire ties to secure to existing cables in theengine compartment.

ImportantUse either the low level or high level input, do notuse both at same time.

Low level inputUse a pair of shielded stereo audio cables with RCAtype jack. Most trunk-mountamplifiers need a 20 feetRCA cable ( appr 5 – 6 me-ters). Most under the seatinstallations require 12 feet( 2 – 3 meters) RCA cables.Avoid placing the RCA cableclose to speaker cables,power cables and remotecontrol cable. Connect to input socket R/L.

X-D40 has dual inputs Front R/L & Rear R/L.Depending on your chosen configuration you canuse either two separate RCA cable, or a single RCAcable together with an Y-split to connect both inputs.

X-D30 has dual inputs, one for the stereo channels(Input R/L), and one for the mono channel (Sub In-put R/L), both inputs must be connected on themono channel input socket.

Input and controls

Low level Input WiringInputs may be low level from the RCA output of the carstereo or high level from the car stereo speaker out-put. Low level = RCA is to prefer for the best soundquality.

Connect left and right speaker wires coming fromthe car stereo to the high level input as shown. Youmust connect both plus and minus as the inputs arebalanced, connecting plus only gives lower level andbad sound quality. By changing the polarity of plusand minus, you can change the phase.

X-D10/20/25/30On these models you connect as in this example:

X-D30On X-D30 the high level signal is fed internally tochannel SUB when using high level input.

X-D40The four channel amplifier is connected likewise,however we have four channels.You can feed two channels from RCA and twochannels using high level input from rear speakercables.

Input Level control

The input level control, 6V – 0,3 V,matches the output of your radio tothe input of the amplifier. After instal-lation is complete, make sure the in-put of the amplifier is turned down allthe way ( counter-clockwise at 6V ).

The high pass filterblocks very lowfrequencies from reachingthe speakers. It is mostlyused at say 60 Hz toprotect small speakers (like 6 inch and smaller )from deep bass.

High Pass filter X-D30, X-D40

Low Pass filter X-D40

The low pass filter ismostly used forsubwoofers. It will allowlow frequencies only andblocks higher frequencies.A typical setting is 50 –70 Hz.

Play a CD, make sure all bass or treble settings orequalizer are flat, and turn the volume of the radioup until you just start to hear distortion. Turn thevolume control down just a bit. On the amplifierincrease the input level control ( clockwise or to theright ) until you just start to hear distortion, then backthe level control just a bit. Now your radio andamplifier levels are matched.

Bass boost XD10, XD20, XD25, XD40

Bass boost is used to increase thebass volume at a low frequency.frequencies. You can select theamplification between 0 dB ( noamplification ) and +18 dB ( fullamplification ).

This function is used to compensate forthe bass box function and to adjust foryour own taste of bass. Set level controlat 0 dB if you want it to be inoperative.

The phase control can be setcontinuously from 0 - 180 degrees.This function is used together withsubwoofers. This is very useful whenyou want to adjust the bass sound forbest front stage image. Start at 0 andturn the control slowly clockwise untilyou experience that the bass sound iscoming from the front. If you don’t getthe result you want, also try to phasereverse the subwoofer connections andmake a new adjustment.

Reconnect Battery

When wiring is complete,reconnect the batterynegative terminal.

If problems occour during the installation, or later,this guide might help you to find out whats´s wrong.

THE AMPLIFIER IS DEAD:1. Check power lead, ground and remote connections at the amplifier using a multi meter.2. Check the battery terminal connections.3. Check the power lead fuse or circuit breaker. If fuse damage continues, inspect the power lead for short circuits.4. Check the amplifier protection fuses. Are these broken change to new ones with the same value. If short circuiting continues, contact your local DLS dealer. A fault may exist in the amplifier.5. To start the amplifier requires a remote voltage of 9-15 volt. Check the voltage with a multi meter.

AMPLIFIER PROTECTION FUSE BLOWS AT LOWVOLUME :1. One or more speaker cables are shorted. Make aninsulation test with a multi meter. The cables must nothave a connection to earth.

THE AMPLIFIER TURNS OFF AFTER 10 - 30 MINU-TES.The amplifier is overheating due to inadequate venti-lation. Check mounting position is free from obstruction.

Do this:1. Move the amplifier to a place with better ventil-

ation.2. Install one or two fans to cool down the heat-

sink.3. Overheating can also be caused by an

impedance load below the level permitted.

NO OUTPUT FROM ONE OR MORE SPEAKERS:

Check the following:1. Balance control position.2. Fader control position.3. Speaker cable connections to both amplifier and

drivers.4. Signal lead plugs and cables.5. Change left and right signal lead plugs in the

amplifier to see if the problem moves to a diffe-rent speaker, the lead has a fault.If the problem remains, the speaker or amplifierare at fault.

Troubleshooting

Test speaker connectionsMake sure the speakers are connected right. Usethe balance control on the head unit to make sureright channel is on right speaker etc. If speakersdon´t play at all, one or both speaker wires maybe disconnected.

Test power wiring

1. Turn on the head unit but do not turn up thevolume. The amplifier power light shouldcome on. If not, check the remote and +12volt wires. Also check the groundconnection.

2. Turn up the head units volume slightly. Allspeakers should operate. if not, check wiringconnections at amplifier and speakers.

NOISE PROBLEMS

WHINING NOISE VARYING WITH ENGINEREVOLUTIONS:

Do this:1. Rewire the power supply (12 V) to source

unit direct from battery.2. Rewire ground wire from source unit to

clean position on chassis.3. Check all power connections to ensure that

they are clean and tight.4. Check quality of system ground connection.5. Install a Power Cap capacitor. This can be

helpful against most noise problems.

CONSTANT WHINING NOISE:

Do this:1. Ensure that all equipment has a common

ground point.2. Check quality of earth strap connection from

battery negative terminal to chassis.3. Disconnect signal cables from amplifier to

see if noise disappears. If so the leads arepicking up noise. Test this by laying a newcable over the seats and reconnecting to theamplifier. If the noise does not return, re-route original cable away from source ofinterference.If noise remains regardless of cable position,try to use so called Quasi-balanced signalcables. DLS PRO-cables areQuasibalanced.

SPEAKER POLARITY CHECK.

All speakers in a car audio system should beconnected in phase (the same polarity). All spea-ker cones must move in the same direction. Out ofphase speakers will cause a lack of bass, and apoor stereo soundstage.

Checking polarity:Hold the - connection of the speaker wire to the -terminal of a 1,5 Volt flashlight battery. Tap the +wire on to the + terminal of the battery, and observethe movement of the cone. The cone should moveoutwards when the wire touches the battery, andinwards when the battery is removed. If it is theother way around, the speaker has been connectedbackwards and it must be removed and connectedcorrectly.If your system also has a subwoofer connectedthrough a passive 6 or 12 dB crossover, try toconnect this with various polarity and judge whatsounds best. The phase shift in passive crossoverssometimes makes it necessary to change polarity.

Professional Tip:Professional Tip:

Professional Tip: Professional Tip:

Installing in trunkWhen installing the amplifier in the trunk, run thepower wires along the same path as the othervehicle wiring. Many cars have insulated channelsfor wiring. you will have to remove the door sill trimand the carpet.

Securing wiresUse wire ties to bundle together when possible.(But never bundle speaker wires or signal cablestogether with power wires.

Professional Tip:

Professional Tip:

Speaker and power wiresDo not run speaker and power wires next to eachother. Power wires can generate a ”siren” sound inthe speakers. Run speaker and power wires onopposite sides of the car.

Crimp connectionsPurchase crimp connectors and crimping tool.Connectors are color coded.

1. Strip 1/4 inch (6 mm) of insulation from the wire.2. Insert into connector3. Crimp tightly
