Positive/negative connection
We recommend a cable cross-section of not
2
less than 6 mm
. Run a standard commer-
cial positive cable to the battery and con-
nect to the fuse holder. Use cable grommets
when passing cables through holes with
sharp edges. Bolt a standard commercial
negative cable to a ground point free of in-
duced noise (car body bolt, body panel) -
not to the negative battery pole. Clean the
contact surface of the ground point down to
bare metal and coat with antiseize graphite
petroleum.
Integral fuses
The integral fuses within the amplifier pro-
tect the final stage and the entire electrical
system in the event of a fault. Never bridge
fuses or replace fuses with a higher current
rating.

+12V
Connect remote amplifier connec-
tion to switchable +12 V power
source.
This enables the amplifier to be switched on
and off with the radio's On/Off switch.
Level control
The Level control enables the input sensi-
tivity of the final stage to be matched to the
output voltage of your car radio preamp out-
put.
The range of adjustment extends from 0.1 V
to 8 V.
Adjust the input sensitivity in accordance with
the manufacturer's specifications when con-
necting the amplifier to other radios.
Important:
Turning the Level control clockwise increas-
es the input sensitivity of the amplifier, and
thereby also the volume. The Level control
is however not a volume control; an increase
in volume is not achieved in the maximum
position, even if this subjectively appears to
be the case. The system merely increases
the volume more quickly when the volume
is turned up on the radio.
Loudspeaker connections
(If the amplifier is to be connected in a
bridged mode, proceed with the section
"Bridged loudspeaker connections".)
As with any audio component, connection
of the amplifier and speakers with the cor-
rect polarity is essential for good bass re-
production. Ensure therefore when connect-
ing that the positive (+) amplifier terminal is
connected to the positive (+) loudspeaker
terminal. The same applies to the negative
(-) terminals. The left-hand amplifier chan-
