Installation
Before you begin the 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 Performance 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.
Check all locations and placements carefully before
making any cuts, drilling any holes or making any
connections.
This is the best direction to
mount the amplifier to get
the best cooling.
Removal of side flanges
In order to fasten the amplifier to the surface and
connect speaker and power cables, the flanges on
the sides must be removed. This is done by
loosening the hex screws on top of the amplifier.
Use a 3 mm hex key.

Troubleshooting
If problems occur 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 connections at

DLS logo on amplifier cooling flange
The DLS logo on top of the amplifier is attached
with two hex. screws. The logo can be removed
and twisted 90 or 180 degrees, and then screwed
back in wanted position. The logo can be mounted
in four different ways to match your installation.
