Welcome!

This owners manual is written in easy english and
uses a lot of drawings to simply the installation and
use of the above amplifiers.

Your DLS amplifiers must be installed correctly in
order to work well. This manual will show you how
to install the amplifier like a pro. Please read the
entire manual before beginning the installation.
Install the amplifier yourself if you feel confident

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.

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.

Routing wires

Stereo

head unit

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.

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

Disconnect Battery

Before starting the instal­lation, always disconnect
the negative terminal of
the battery.

Professional Tip:

If amplifier installation kits are available with dif­ferent 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 CC-2, CC-4 &
CC-44 accept AWG 5 cables, so If possible buy
AWG 5 = 16 mm
CC-500 & CC-1000 accepts AWG 2 = 33 mm
wer 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.

Tools and material needed

Tools:

 Flat and Phillips screwdrivers
 Wire cutter
 Wire stripper
 Electric drill with drills
 Crimping tool
 Digital multimeter or test lamp
 Wire brush, scraper or a piece

of an abrasive sheet to remove
paint for a good ground connection
 Grease to protect the ground
connection from oxidation

Material:

 Speaker wire: minimum
12 AWG = 4 mm
nected to CC-500 / CC-1000
13 – 16 AWG = 1,5 - 2,5 mm
speakers
 Sheet metal screws for mounting the
amplifier to the amplifier board and the
amplifier board to the car + some extra
for fuse holder, amplifier ground etc.

 Electrical insulation tape
 ½ inch thick plywood or particle board

for the amplifier to be mounted upon.

Amplifier installation kit:

If available,buy an amplifier installation kit. It con­tains normally all you need. This is what you have
to buy if you buy the items separately
 20- 25 feet = 6-7.5 meter power cable,
minimum AWG 8 = 10 mm
 1 pc of fuseholder to install close to the
car battery + fuse 40 -50 Ampere.
 20 feet of AWG 15 = 1,5 mm
remote turn on / off cable from radio.
 RCA-cable for input from radio.

- 20 feet or 5 meter for trunk installa
tions

-12 feet or 2 – 3 meter for under seat
installations
 Two ring crimp terminals (RT22) –one
for connection to the battery plus and
one for the amplifier ground connec­ tion.
 Four to eight splicers to connect

ker cables to high level input cable, if
high level input is used.
 Wire ties

Fuses

Use only ATC blade type fuses
of the same value when repla­cing a blown fuse.
CC-500, CC-1000 & CC-44 has
no internal fuse so we recom­mend the use of an external
fuse.

Power wiring

mm

power cable. Use a ring crimp terminal to
connect to battery. The AWG4 cable can use an
80 Amp fuse, if the cable is smaller, the fuse va­lue must be lower (see table on previous page).
This fuse is to procect from cable fire!

Be sure to use a rubber grommet or a plastic insu­lating tube where the cable passes the firewall or
other places where it can be easily jammed.
Use wire ties to secure to existing cables in the
engine compartment.

Ground Terminal ( GND )

Connect to a good chassis ground. The ground
connection should be clean, unpainted metal to
provide a good electrical connection. Use a wire
brush, a scraper or a piece of an abrasive sheet
to clean the metal. Use a lock washer or two to
secure contact. Protect with silicon grease or by
paint applied afterwards.

the amplifier is turned on.

Remote terminal ( REM )

High Level Input wiring

For RCA cable signal input:

Connect the radio power antenna lead = remote
turn on/off from the car stereo to the amplifier
remote connection. This turns on the amplifier
whenever the car stereo is turned on. You can either
use the built in remote cable in the RCA cable itself
or use a separate cable.
Sometimes a small disturbance may enter the amp­lifier coming from the remote voltage , through the
built in remote wire and into the RCA cable. Thus
we recommend to use a separate remote wire and
run the RCA lead separate from remote wire, power
cables and speaker cables.
If there is no remote voltage available from the
stereo, you must connect to the ignition key through
the radio or any accessories fuse.
When high level input is used the amplifier starts
automatically when your car stereo is switched on.

To head unit Power
Antenna lead or
remote output.

A cable up to AWG 14 (2,5 sq
mm) fits the amplifier remote
(REM) terminal.

Low level Input Wiring

Inputs may be low level from the RCA output of the car
stereo or high level from the car stereo speaker output.
Low level = RCA is to prefer for the best sound quality.

Important

Use either the low level or high level input, do not
use both at same time.

Low level input

Use a pair of shielded stereo audio cables with RCA
type jack. Most trunk-mount amplifiers need a 20
feet RCA cable ( appr 5 – 6 meters).
Connect to input socket CH1 / CH2 on CC-2.
Or R/ L on CC-500 /

CC-1000.

For High Level input:

Most headunits are pre-installed from the car factory
and have no RCA output, in this case you can take
the signal from the speaker output instead.
Use either a sepatate remote cable or let the high
level signal automatically start the amplifier.

Connect left and right speaker wires coming from
the car stereo to the high level input as shown. You
must connect both plus and minus as the inputs are
balanced, connecting plus only gives lower level and
bad sound quality. By changing the polarity of plus
and minus, you can change the phase. Connect the
black wire to minus ground.

CC-500 / CC-1000 / CC-2

On these two models you connect as in this example:
CC500 / 1000 are marked R and L instead of CH1
/ CH2.

however we have four channels.

or all channels from high level input.

CC-4 / CC-44 has dual inputs CH1 / CH2 / CH3

you can use either two separate RCA cables, or a
single RCA cable together with an Y-split to con­nect both inputs.
