Congratulations, you have just purchased the finest mobile audio amplifier that today´s technology can
offer. DLS offers a series of high quality car audio products for real music lovers, and we are sure that you
will enjoy a high class car sound for many years.
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 ears.
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
100 dB
Chain saw
120 dB
Rock band live concert
140 dB
Gunshot blast, jet plane
Installation
Before you begin to 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.
Amplifier location
Important
Allow air circulation around the amplifier.
The DLS ULTIMATE amplifiers have a great
flexibility in mounting but the best is to mount it
somewhere 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 upside down under
the hat rack.
In the amplifier case there are four mounting holes.
If the surface where you intend to mount the
amplifier isn´t big enough you can mount it on a
separate fibre board or similar. This will also isolate
the amplifier chassies from ground.
WARNING!
Check all locations and placements carefully before
making any cuts, drilling any holes or making any
connections.

rent 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.
