CAUTION!

Some of our amplifiers are capable of producing a sound pressure level that can cause permanent
damage to your hearing system. High sound pressure levels combined with long time listening can give
permanent damage to your hearing system. Choose a listening level that is comfortable for your ear.
To establish a safe level:
Start your volume control at a low setting. Slowly increase the volume until you can hear the music
comfortly and clearly , without any distortion. Sudden sound shocks are dangerous.

The following noises can be dangerous with constant exposure:

90 dB Subway, motorcycle, lawn mover 4 hours max
100 dB Chain saw 2 hours max
120 dB Rock band live concert 30 minutes max
140 dB Gunshot blast, jet plane 0 minutes

GENERAL, POWER CABLING

1. General product information

Thank you for buying a DLS amplifier. This amplifier
is a high quality product and is a result of many
years of experience of building high quality sound
products for vehicles.

We recommend you to carefully read this manual
before you start to install. Be sure to follow all
recommendations in the installation section. If you
do so we are sure that you will be able to enjoy a
perfect sound for a long time,.

2. Installation preparation

2.1 LOCATION

We recommend you to do a careful planning before
you start to install this equipment.
Choose a location for the amplifier which will allow
plenty of air to circulate around the fins on the top of
the case. V ertical mounting is to prefer. Do NOT mount
the amplifier upside down under the hat rack.
In the amplifier case there are double mounting holes
to make the installation job easier. The screws
supplied in the plastic bag are self drilling when used
with an electric screwdriver .
If the surface where you intend to mount the amplifier
isn´t big enough you can mount the amplifier on a
separate fibre board or similar. This will also isolate
the amplifier chassies from ground.

NOTE! Before you start drilling, make sure that
there are no fuel or brake lines or wiring looms
behind where you intend to drill.

2.2 POWER CABLES

The DC power wiring is extremely important. It is
essential that the amplifier at all occassions gets all
the power it needs without voltage drop, otherwise
both the dynamics and the good sound will be lost.
A poor battery can also cause a bad sound
reproduction, escpecially in the bass range. Some­times it is necessary to mount an extra battery.
The speaker cable connections requires a 2 mm hexa­gon key to connect the terminals, and the power cable
connections require a 4 mm hexagon key .

In most cases a so called ”Power Cap” can be useful.
It is an energy storage capacitor designed to supple­ment audio amplifiers during high current demand. The
overall bass response of your audio system will be
enhanced with the use of this due to it´s ability to
store a large amount of current and discharge it in a
short period of time.

In the table below you will find suitable cable and fuse
sizes for different cable lenghts.
The gold plated terminals will directly recieve
power cables up to 21 mm2 (4AWG).
Mount the fuse holder included in the amplifier on the
DC -cable near the positive battery terminal. Use the
same cable size from the negative amplifier terminal
and connect to the nearest earth point.
The Fuse holder accepts cables up to 21mm2 if you
remove the inner bushing. If you are using heavier
cables use another type of fuse holder or cut some of
the strands in the cable.
Make sure to have a good earth contact, if necessary
clean the metal from paint etc. A poor earth contact
can cause damage to other parts in the system, for
example the head unit if the earth current is forced to
pass through the shield of the signal cable.

Amplifier Fuse value Fuse holder

D 1000 AGU 80 A FH1/FH1B

A cable of a certain size can´t have an oversized fuse,
then the cable gets too warm before the fuse blows.

Max fuse values for different cable sizes:

6 mm2 (9 AWG) 25 A
10 mm2 (7AWG) 40 A
16 mm2 (5AWG) 60 A
21 mm2 (4AWG) 100 A
33 mm2 (2AWG) 140 A
42 mm2 (1AWG) 200 A

If you have more than one amplifier in the system
you must increase the cable size and fuse compared
to the table. When connecting two or more amplifiers
use some of the DLS Fuse blocks with built in fuses
to split the power to each amplifier. The short cable
from the Fuse block to the amplifier can have a smal­ler size for easier installation.
Don´t connect to battery before you have double
checked all connections.
