POWERED SUBWOOFER SYSTEM
SUB1
IMPORTANT NOTES PRIOR TO INSTALLATION
• This device is only suited for a 12 volt system with negative ground.
• The radiated heat while operation requires sufficient air circulation at the place of installation. It is very im-
portant that the heat sink fins do not have contact with any metal parts or any surfaces which could impair
air circulation. The amplifier may not be installed in small closed location or spaces without air circulation.
We recommend the installation in the vehicle’s trunk. Ensure sufficient protection against vibrations, dust
and dirt.
• Ensure that the input and output cables are sufficiently separated from the power supply cables. Otherwise
interferences may occur.
• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the amplifier depends on the quality of installation. Preferably consult an
expert to install the system.
• Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat
belts, gas tank or the like.
POWER SUPPLY AND TURN-ON-CONNECTION
ATTENTION: Before you start with the installation, disconnect the ground connection from the ve-
hicle’s battery in order to prevent short circuits. Use the enclosed cable plug to connect each terminal.
The power wiring which is usually installed in on-board car networks is not sufficient for a power amplifier‘s
demands. Make sure that the power wires to GND and to the +12 V terminal has been sufficiently specified.
First connect the GND terminal
[ 1 ]
of the amplifier to an appropriate ground connection at the chassis. To
ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause
malfunctions or interferences noise and distortion.
Then connect the +12 V terminal
[ 2 ]
of the amplifier with the battery by using an appropriate cable including
an in-line fuse. This fuse
[ 4 ]
should be located very close to the battery
[ 3 ]
; for safety reasons not more than
30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been
accomplished.
Then connect the remote turn-on-wire
[ 5 ]
from the head unit with the amplifier‘s REM terminal. A cable with a
cross-section of 0.5 mm

is adequate.
