Installation

Before you begin installation

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.

Disconnect Battery

Before starting the instal-
lation, always disconnect 
the negative terminal of 
the battery.

Professional Tip:

If amplifier installation kits are available with  dif-
ferent 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.
The amplifier power terminals on CCi2, CCi4 
& CCi44 / CCi44-40 accept AWG 5 cables, so 
If possible buy AWG 5 = 16 mm

power cable. Both the positive wire and the 
ground wire must have the same size. 

NOTE!
To avoid cable fire, be sure not to oversize the 
main fuse value for the power wires.

The DLS 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 be-
fore making any cuts, drilling any holes or making 
any connections.

IMPORTANT!
Use the metal screws  coming with the amplifier 
when you do the install. Do not use oversized 
screws.
