DEAR CUSTOMER,
We congratulate you on acquiring this MAC AUDIO Car HiFi Product.
Please read these instructions carefully so as to ensure optimum and disturbance-free functioning of
the appliance. Technical modifications reserved.
IMPORTANT INFORMATION TO BE HEEDED BEFORE INSTALLATION
· This device is only suitable for connection to a 12-volt system with negative earth.
· Ensure that the input / output cables are far enough away from the power supply cables, as this can
otherwise lead to interference.
· Make sure that the fuse and controls are accessible after installation.
· The performance and reliability of the system depends on the quality of the installation. The system should
therefore be installed by a professional where several speakers or a complex multi-channel system are
involved.
POSITIONING AND SECURING THE SUBWOOFER
Place the subwoofer in a position where adequate ventilation of the amplifier module is guaranteed. Make sure
it rests on an even surface. The cones and the bass reflex opening should not be placed directly against the car's
interior walls.
Make sure that the subwoofer is secured in such a way that it cannot slip or slide. Damage resulting
from sudden changes in speed (e.g. hard braking) is not covered under the terms of our guarantee. Use
the securing device supplied for this purpose.
CONNECTING TO THE POWER SUPPLY (FIGURE 1)
Before installation: Remove the positive terminal from the car battery first in order to avoid short
circuiting.
Standard car wiring is normally not sufficient for the power requirement of the integrated amplifier. Make sure
that the wiring to the earth and +12V is of the correct gauge. 6 mm² cable is the minimum requirement for the
connection from the battery to the amplifier terminals (for long cable runs over 4 meters, 10 mm² gauge cable
should be used).
First make the connection between the amplifier's earth terminal (9) and the negative terminal on the battery.
To ensure a good connection, any residual dirt should first be carefully removed from the battery terminals. A
loose connection can result in malfunction or interference noise and distortions.
A power cable with an integrated fuse is then connected between the +12V (7) terminal on the amplifier and the
battery's positive terminal. An additional fuse should be positioned at a maximum distance of 60 cm from the
car battery. This is only to be inserted once all the installation work, including the connecting of the speakers,
has been completed.
Now connect the car radio's +12v remote control cable (P-con, Power Antenna, or similar) to the REM (8) control
socket on the amplifier. A 0.75 mm² gauge cable is sufficient for this REMOTE connection.
The REMOTE input is not connected if the active subwoofer is activated by the speaker output of a car radio or
an amplifier, i.e. with high-level operation of the active subwoofer.
NF CABLE
When fitting the audio cable in the vehicle between the car radio's cinch output and the cinch input on the
amplifier, it should be ensured that the audio and power supply cables are, as far as possible, not laid on the
same side of the car. It is better to install these far apart from each other, i.e. the power cable in the left cable
duct and the audio cable in the right cable duct or vice versa. This reduces the feed-through of interferences to
the audio signal.
