Welcome!

This owners manual is written in easy english and
uses a lot of drawings to simply the installation and
use of the above amplifiers.

Your DLS amplifiers 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.

Troubleshooting

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.

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.

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.

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.

Check all locations and placements carefully before
making any cuts, drilling any holes or making any
connections.

Disconnect Battery

Before starting the instal­lation, always disconnect
the negative terminal of
the battery.




 Wire stripper




 Electric drill with drills




 Crimping tool






 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 oxidation

Material:

 Speaker wire: minimum

12 AWG = 4 mm2 for subwoofers
13 – 16 AWG = 1,5-2,5 mm2 for other
speakers

 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 8 = 10 mm2 or heavier

 1 pc of fuseholder to install close to the

car battery + fuse 50 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

 Two min. 8 gauge ring crimp terminals –one

for connection to the battery plus and one
for the amplifier ground connection.

 Two heavy fork crimp terminals to connect

+ and – to amplifer – but you do only need
them if you use heavy cable or to make the
installation look nicer.

 Four to eight fork crimp terminals to

connect the speaker cables – but you do
only need them if you use heavy cables or
want the installation to look nicer.

 One fork crimp terminal to connect the

remote wire to the amplifier, but you need
only to make it look nicer.

 Four to eight splicers to connect speaker

cables to high level input cable, if high level
input is used.

 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 4 = PL 21 mm2 (or heavier)
cable for best performance.
