Your DLS amplifier must be installed correctly in order to work well. This manual will show you how to
install the amplifier like a pro. Please read the entire
manual before beginning the installation.
Install the amplifier yourself if you feel confident with
our instructions and if you have the proper tools.
However if you feel unsure, turn over the installation job to someone better suited to it.
Warranty Service
This amplifier is covered by warranty, depending
on the conditions in the country where it is sold. If
the amplifier is returned for service, please include
the original dated receipt with the product.
For technical assistance ask the shop where the
product was sold or the distributor in your very country.
You can always phone the DLS Helpdesk in Sweden
+ 46 31 84 00 60 or send an e-mail to info@dls.se.

Installation
Before you begin the install
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.
CAD11, CAD15
Amplifier location
Important
Allow air circulation around the amplifier.
The DLS Peformance 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.
This is the best direction to
mount the amplifier to get
the best cooling.
DLS logo on amplifier cooling flange
The DLS logo on top of the amplifier is attached
with two hex. screws. The logo can be removed
and twisted 90 or 180 degrees, and then screwed
back in wanted position. The logo can be mounted
in four different ways to match your installation.
Removal of side flanges
In order to fasten the amplifier to the surface and
connect speaker and power cables, the flanges on
the sides must be removed. This is done by
loosening the hex screws on top of the amplifier.
Use a 3 mm hex key.
Disconnect Battery
Before starting the installation, always disconnect
the negative terminal of
the battery.

Remove these
screws using a 3
mm hex. key for
removal of side
flange. Remount
after fastening the
amplifier and
connection of the
speaker and power
cables.

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
Routing wires
Stereo
head unit
½ inch thick plywood or particle board for
the amplifier to be mounted upon.
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 0 (50 mm2 ) for CAD15 &
4AWG (21mm2) for CAD11
1 pc of ANL fuseholder to install close to the
car battery + fuse. CAD11= 150A, CAD15=
200A
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 ring crimp terminal
for the amplifier ground connection.
High current draw
The CAD11 / 15 are mono amplifiers 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.
Wire ties
Insulating grommet or insulating tube
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 0 = 50 mm2 (or heavier) cable
for best performance of CAD15, or AWG4 (21 mm2)
for CAD11.

Power and Outputs
Power terminal ( +12V)
Connect the fuse holder as close to the vehicle
battery + as possible, using AWG 0 = 50 mm2.
Use ring crimp terminal cable to connect to
battery +. Apply silicon grease to the fuse to
prevent corrosion. Use a fuse holder for ANL
fuses like the DLS FH2B.

fuse holder
Connect the battery cable to the +12 Volt on the
amplifier. If you want to improve the power capacity
you can add a Power capacitor of 1 Farad in parallel
with the DC input. See the drawing on page 7.
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 wire ties to secure to existing cables in the
engine room.

DC input
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.
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.

Connect to a good chassis 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. Use the same cable area for the
ground cable as for the + cable.

Power Light / Protect light
The power light (green ) comes on when
the amplifier is turned on.
The protect light ( red ) comes on
when the amplifier shuts down from
overheating or short circuit.
Fuses
Use only ATC blade
type fuses. CAD11 uses
four 30 amp fuses.
