DLS 1072 - User Manual

CLASSIC SERIES
CAR AUDIO SPEAKERS
WELCOME
Thank you for buying a DLS CLASSIC speaker.
This manual will show you how to do a correct installa-
tion. Please read the entire manual before beginning the
installation.
Install the speakers 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
Mount the speakers in the door or in the dashboard of
your car. Normally they will fit in the facory pre-made
mounting holes. If you want an improved sound reinforce
with a baffle of MDF-board or similar. An installation high
up on the door side is to be prefered. An alternative in-
stallation is in so called kick panels down on each side of
the floor with the speakers facing up- and inwards
towards the listener.
For two- or three way speaker systems with separate
tweeter an installation of the tweeter close to the bass/
mid element is to be prefered. The tweeter can also be
installed on the dash-board, or recessed in the door with
the accessories in the tweeter box.
It is important to fasten the speakers properly in order to
avoid bad sound or rattling.
For speakers with separate filters in boxes or similar it is
vital that they are attached properly to the interior of the
vehicle to avoid rattling. Don´t place them close to the
internal wiring of the car, this can cause interference.
Avoid to install filter boxes in the door sides because
they can easily be broken because of rattling or
moisture. Make sure the cables don´t get jammed
causing a short circuit to ground. This can damage the
output circuits of the head unit or amplifier.
All models except for 257 and 457 comes with grilles.
The tweeter installation for kits with separate tweeter is
described on last page, or in the instruction sheet
coming with the tweeters.
