Installation
Before you begin installation
Before you begin you need to read the manual, to have
some tools, cables and other material available. There
is one such list of material on the following page.
Amplifier location
CAD1000
Troubleshooting
If problems occur 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 LOW
VOLUME :
1. One or more speaker cables are shorted. Make an
insulation test with a multi meter. The cables must not
have a connection to earth.
Important
Allow air circulation around the amplifier.
The DLS Classic series of amplifiers have a
compact design that allows great flexibility in
mounting. You can mount it under a seat or in the
trunk.
When you select a location, do remember that the
amplifier generates a lot of heat.
Choose a location where air can circulate freely
around the amplifier. Do not cover the amplifier
with carpets or hide behind trim panels.
Do not mount the amplifier in an inverted or upside
down position.
Check all locations and placements carefully before
making any cuts, drilling any holes or making any
connections.
Disconnect Battery
THE AMPLIFIER TURNS OFF AFTER 10 - 30 MINUTES.
The amplifier is overheating due to inadequate ventilation. 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 heatsink.
3. Overheating can also be caused by an
impedance load below the level permitted.
NO OUTPUT FROM THE SPEAKERS:
Check the following:
1. Fader control position.
3. Speaker cable connections to both amplifier and
subwoofers.
4. Signal lead plugs and cables.
Before starting the installation, always disconnect
the negative terminal of
the battery.

Tools and material needed
Tools:
Flat and Phillips screwdrivers
Wire cutter
Wire stripper
Electric drill with drills
Crimping tool
Digital multimeter or test lamp
Wire brush, scraper or a piece
of an abrasive sheet to remove
paint for a good ground connection
Grease to protect the ground
connection from corrosion
Material:
Speaker wire: minimum
12 AWG = 4 mm2 for subwoofers
Sheet metal screws for mounting the
amplifier to the amplifier board and the
amplifier board to the car + some extra
for fuse holder, amplifier ground etc.
Electrical insulation tape
½ inch thick plywood or particle board for
the amplifier to be mounted upon.
Routing wires
Stereo
head unit
Amplifier installation kit:
If available,buy an amplifier installation kit. It
contains normally all you need. This is what you
have to buy if you buy the items separately
20- 25 feet = 6- 7.5 meter power cable,
preferably AWG 4 = 21 mm2 or heavier
1 pc of fuseholder to install close to the
car battery + fuse 100 Ampere.
20 feet of AWG 15 = 1,5 mm2 wire for
remote turn on / off cable from radio.
RCA-cable for input from radio.
- 20 feet or 5 meter for trunk installations
-12 feet or 2 – 3 meter for under seat
installations
One min. 8 gauge ring crimp terminal
for the amplifier ground connection.
Wire ties
Insulating grommet or insulating tube
High current draw
The CAD1000 is a mono amplifier with high power
output. The current draw is also high so you must make
sure that your vehicles power system (battery and
alternator) can provide all the power you need. If you
have a bad battery or alternator in can result in a poor
sound or even worse, a broken battery or alternator.
Professional Tip:
If amplifier installation kits are available with different size of power cable, chose the most heavy
power cable to improve sound quality and to allow
more amplifiers to be installed now or later.
If possible buy AWG 4 = PL 21 mm2 (or heavier)
cable for best performance.

Power terminal ( +12V)
Connect the fuse holder as close to the vehicle
battery + as possible, using AWG 4 = 21 mm2 or
heavier cable. Use ring crimp terminal cable to
connect to battery +. Apply silicon grease to the
fuse to prevent corrosion

fuse holder
Connect the battery cable to the +12 Volt on the
amplifier.
Be sure to use a rubber grommet or a plastic
insulating tube where the cable passes the firewall
or other places when it can easily be jammed.
Use ty-wraps to secure to existing cables in the
engine compartment.
For RCA cable signal input:
Connect the radio power antenna lead = remote
turn on/off from the car stereo to the amplifier
remote connection. This turns on the amplifier
whenever the car stereo is turned on.
You can either use the built in remote cable in the
RCA cable itself or use a separate cable.
Sometimes a small disturbance may enter the
amplifier coming from the remote voltage , through
the built in remote wire and into the RCA cable.
Thus we recommend to use a separate remote wire
and run the RCA lead separate from remote wire,
power cables and speaker cables.
You can either use a crimp fork terminal or insert
the cable directly into the amplifier terminal. If there
is no remote voltage available from the stereo, you
must connect to the ignition key through the radio
or any accessories fuse.
For High Level input:
We recommend you to connect the remote wire
as described above. The amplifier will produce soft
on / soft off operation this way. You must set the
Hi level/Low level switch to Low level position in
this case.
In the case that there is no remote voltage available
from the car stereo or you want to simplify the
installation, the amplifier can be turned on/ turned
off by the high level input voltage. This is done
when the Hi level/Low level switch is set to Hi level
position. There is a small disadvantage that this
function gives soft turn off operation but some plop
sound when switching off.
+12V REM GND
+12V RMT GND
Ground Terminal ( GND )
Connect to a good chasis ground. The ground
connection should be clean, unpainted metal to provide a good electrical connection. Use a wire brush,
a scraper or a piece of an abrasive sheet to clean
the metal. Use a lock washer or two to secure
contact. Protect with silicon grease or by paint
applied afterwards.

Input and controls
Input Wiring
Inputs may be low level from the RCA output of the
car stereo or high level from the car stereo speaker
output.Low level = RCA is to prefer for the best sound
quality.
Important
Use either the low level or the high level input, do
not use both at same time.
Low level input
Use a pair of shielded stereo audio cables with RCA
type jack. Most trunk-mount
amplifiers need a 20 feet
RCA cable ( appr 5 – 6 meters). Most under the seat
installations require 12 feet (
2 – 3 meters) RCA cables.
Avoid placing the RCA cable
close to speaker cables,
power cables and remote
control cable. Connect to input socket A & B.
Input Level control
The input level control, 5V – 0,5 V,
matches the output of your radio to
the input of the amplifier. After instal-
Level
2V 0,7V
lation is complete, make sure the input of the amplifier is turned down
5V
0,5V
all the way ( counter-clockwise at 5V
). Play a tape or CD, make sure all bass or treble
settings or equalizer are flat, and turn the volume
of the radio up until you just start to hear distortion.
Turn the volume control down just a bit. On the
amplifier increase the input level control ( clockwise
or to the right ) until you just start to hear distortion,
then back the level control just a bit. Now your radio and amplifier levels are matched.
Subsonic filter
High Level Input
Connect left and right speaker wires coming from
the car stereo to the high level input as shown. Y ou
must connect both plus and minus as the inputs
are balanced, connecting plus only gives lower level
and bad sound quality . By changing the polarity of
plus and minus, you can change the phase.
High Input
Hi level input plug on amp.

Automatic turn on when using high level input.
With the Hi/Low input swich set to Hi, the amplifier turns
on automatically on high input. Y ou dont need to connect
a separate remote wire from your head unit.
When using High Level input:
Set the switch to position ”Hi / Level”
When using Low level input:
Set the switch to position ”Low / Level”
If the switch is set to wrong position, the amplifier
still works, but the risk for disturbances or distortion
increases.
RCA Output
Input Output
Use RCA Outputs to

BB
connect additional
amplifiers.
The Subsonic filter blocks the
very deepest frequencies from
reaching the subwoofers. It has a
variable frequency from 10 to 60
Hz. A typical setting is 25-30 Hz.
Low Pass Filter
The LPF ( low pass filter ) allow
low frequencies only and blocks
higher frequencies. A typical setting is 60 – 80 Hz. Choose the setting that sounds best in your car.
you can select between two different slopes, 12 dB/ octave or 24
dB/ octave.
Phase control
The phase control can be set
continuously from 0 - 180 degrees. This
is very useful when you want to adjust
the bass sound for best front stage
image.
Start on 0 and turn the control slowly
clockwise until you experience the bass
sound coming from the front.
It is also useful when you have more
than one CAD1000 and want all
speakers to play in phase.
You may have to change the polarity of
the speaker connection to get the best
result.

Bass boost control on CAD1000
Bass boost control is used to set
the bass volume. Y ou can select the
amplification between 0 dB and +6
dB.
This function is used to compensate
for the bass box function and to
adjust for your own taste of bass. Set
level control at 0 dB if you want it to
be inoperative.

Remote level control on CAD1000
The audio level can be adjusted from the front seat
by using the remote level control box. Connect the
cable coming with the amplifier between the control
box and remote connector on the amplifier.

Before you finish the installation, you should do the
following tests to make sure the wiring is correct and
everything is operating properly.
Reconnect Battery
When wiring is complete,
reconnect the battery
negative terminal.
Test power wiring
1. Turn on the head unit but do not turn up the
volume. The amplifier power light should
come on. If not, check the remote and +12
volt wires. Also check the ground
connection.
2. Turn up the head units volume slightly. All
speakers should operate. if not, check wiring
connections at amplifier and speakers.

Professional Tip:Professional Tip:
NOISE PROBLEMS
WHINING NOISE VARYING WITH ENGINE
REVOLUTIONS:
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 are
picking up noise. Test this by laying a new
cable over the seats and reconnecting to the
amplifier. If the noise does not return, reroute original cable away from source of
interference.
If noise remains regardless of cable position,
try to use so called Quasi-balanced signal
cables. DLS PRO or ULTIMATE cables are
quasibalanced.
SPEAKER POLARITY CHECK.
All speakers in a car audio system should be
connected in phase (the same polarity). All speaker cones must move in the same direction. Out of
phase speakers will cause a lack of bass, and a
poor 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 observe
the movement of the cone. The cone should move
outwards when the wire touches the battery, and
inwards when the battery is removed. If it is the
other way around, the speaker has been connected
backwards and it must be removed and connected
correctly.
If your system also has a subwoofer connected
through a passive 6 or 12 dB crossover, try to
connect this with various polarity and judge what
sounds best. The phase shift in passive crossovers
sometimes makes it necessary to change polarity .

Professional Tip: Professional Tip:
Installing in trunk
When installing the amplifier in the trunk, run the
power wires along the same path as the other
vehicle wiring. Many cars have insulated channels
for wiring. you will have to remove the door sill trim
and the carpet.
Securing wires
Use wire ties to bundle together when possible.
(But never bundle speaker wires or signal cables
together with power wires.
Professional Tip:
Crimp connections
Purchase crimp connectors and crimping tool.
Connectors are color coded.
1. Strip 1/4 inch (6 mm) of insulation from the wire.
2. Insert into connector
3. Crimp tightly
Professional Tip:
Speaker and power wires
Do not run speaker and power wires next to each
other. Power wires can generate a ”siren” sound in
the speakers. Runs speaker and power wires on
opposite sides of the car.
