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,.

Sections 2 - 4 in this manual are common for both
amplifiers. In section 5 & 6 you will find connection
diagrams for each amplifier model.

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. Vertical 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.

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. Some-
times it is necessary to mount an extra battery.
All cable connections requires a 2 mm hexagon key
to connect the terminals.

In most cases a so called ”Power Cap” can be useful.
It is an energy storage capacitor designed to supple-
ment 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.

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 smal-
ler size for easier installation.
Don´t connect to battery before you have double
checked all connections.

In the table below you will find suitable cable areas
and fuse sizes for different cable lenghts.
The gold plated terminals will directly recieve
power cables up to 16 mm

2

 (5AWG).

Mount a fuse holder (DLS FH 1 or similar) 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.
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.

GENERAL, POWER  CABLING

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 mm
