DLS CLASSIC CAD11
Y our 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.

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
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.

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 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. T o 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:
One or more speaker cables are shorted. Make an
insulation test with a multi meter. The cables must
not have a connection to earth.
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 heat sink.
3. Overheating can also be caused by an
impedance load below the level permitted.
No output from the speakers:
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.
Disconnect Battery
Before starting the installation, always disconnect
the negative terminal of
the battery .
2
Check the following:
1. Speaker cable connections to both amplifier and
subwoofers.
2. Signal lead plugs and cables.
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.

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 A WG = 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 A WG 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
High current draw
The CAD1 1 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.
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 4 = PL 21 mm2 (or heavier)
cable for best performance.
