How to install and operate the

X-program amplifiers

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 X-program 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 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.

Warranty Service

This amplifier is covered by warranty, depending
on the conditions in the country where it is sold. If

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.

2

Disconnect Battery

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

The X-program 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.

X-logo on amplifier cooling flange

The X-logo on the amplifier top is attached with
two 1 mm 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.

Mounting

Fasten the amplifier to the surface using the four
separate brackets coming with the amplifier. The
brackets are attached to the amplifier with screws
and can be directed in two ways, see figure:

Mount the flanges this way, or this way.

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 accept AWG 4
cables directly, so If possible buy AWG 4 = 21
mm2 cable for best performance.
Both the positive wire and the ground wire must
have the same size. To avoid cable fire, be sure
not to oversize the main fuse value for the power
wires.

THE DC-FEED

Maximum main fuse values for different cable
sizes.

6 mm2 (9 AWG) :25 A 10 mm2 (7AWG) :40 A
16 mm2 (5AWG) :60 A 21 mm2 (4AWG) :100 A
33 mm2 (2AWG) :150 A 42 mm2 (1AWG) :200 A

power cable. Use a ring crimp terminal cable to
connect to battery +. Apply silicon grease to the
fuse to prevent corrosion. 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).

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 power light (green ) comes on when
the amplifier is turned on.

The protect light ( red ) comes on
when the amplifier shuts down from
overheating, or a short circuit ( spea­ker failure)

Fuses

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.
You can insert the cable directly into the amplifier
terminal. If there is no remote voltage available from
the stereo, you must connect to the ignition key
through the radio or any accessories fuse.

For High Level input:

We recommend you to connect the remote wire as
described above. The amplifier will produce soft on
/ soft off operation this way.
In the case that there is no remote voltage available
from the car stereo or you want to simplify the in­stallation, the amplifier can be turned on/ turned off
by the high level input voltage. This is done
automatically when the head unit is turned on. There
is a small disadvantage that this function gives soft
turn on operation but some pop sound when
switching off.

GND REM +12V Fuse

A cable up to AWG 4 fits directly in the amplifier +
12 V terminal, tighten with the hex screw.

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.

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). Most under the seat
installations require 12 feet
( 2 – 3 meters) RCA cables.
Avoid placing the RCA cable
close to speaker cables,
power cables and remote
control cable. Connect to input socket R/L.

X-D40 has dual inputs Front R/L & Rear R/L.
Depending on your chosen configuration you can
use either two separate RCA cable, or a single RCA
cable together with an Y-split to connect both inputs.

X-D30 has dual inputs, one for the stereo channels
(Input R/L), and one for the mono channel (Sub In­put R/L), both inputs must be connected on the
mono channel input socket.

Input and controls

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.

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.

X-D10/20/25/30

On these models you connect as in this example:

X-D30

On X-D30 the high level signal is fed internally to
channel SUB when using high level input.

X-D40

The four channel amplifier is connected likewise,
however we have four channels.
You can feed two channels from RCA and two
channels using high level input from rear speaker
cables.

Automatic turn on when using high level input.

The amplifier turns on automatically when using high
level input, you dont need to connect a separate
remote wire from your head unit.

For a soft turn ON /OFF operation we recommend
you to use a remote wire, if this is available.

High Level Input wiring

Parallel input on X-D30

If you don’t have dual line cables to
front and sub Input you can use a
single line cable. Connect to the ste­reo input sockets and set the Parallel
input swich to position P-sub and the
signal is fed to the Sub input socket
automatically.
