Safety notes
Please observe the following safety notes during the instal�
lation and connection.
� Disconnect the negative pole of the battery! Observe
the safety notes of the vehicle manufacturer.
� When you drill holes, ensure that you do not damage
any vehicle components.
� If the positive and negative cable are extended, ensure
that the cross section is not less than .5 mm
� An incorrect installation can result in malfunctions of the
electronic vehicle systems or your car sound system.
Installation and connection instructions
With respect to accident safety, the THb 00A must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers sufficient air circulation for cooling
the amplifier.
The THb 00A must not be installed on rear shelves, rear
seats or other locations that are open to the front.
The installation location must be suitable to accept the
accompanying screws and provide a firm support (see
page  / Fig. 1).
The amplifier power cable must be fitted with a fuse no
more than 30 cm from the battery to protect the vehicle
battery in case of a short circuit between power amplifier
and battery. The fuse of the amplifier protects only the
amplifier, not the vehicle battery.
Switching on/off
One of the special features of the THb 00A is its automatic
switch-on.
The subwoofer box automatically switches on if a music
signal is received.
If there is no music signal for more than 60 seconds, the
THb 00A automatically switches off.
Connection (see p. 2 /Fig. 2)
Connection 6 is connected to the positive pole of the
battery and connection 7 to negative vehicle ground.
The control of the THb 00A should ideally be a two�
channel control, either via the preamplifier outputs or the
loudspeaker outputs of the car sound system. A control
solely via the right or left channel is also possible since the
low�frequency portion of the music is generally identical
on both channels.
The preamplifier outputs are connected to the cinch (RCA)
sockets of the woofer box via a shielded sound cable. With
control via the loudspeaker outputs, the input connections
of pos. 9/: are fed to the closest loudspeaker cables
(front or rear) on the left and right. They are separated
and connected to the input connections. The polarity of
the + or � connections must be observed. Bridge output
stages (BTL) can also be connected directly without an
additional adapter.

Settings
The following control setting is recommended as basic
setting before putting the device into operation: Sensitivity
(gain) pos. 1 to minimum, phase pos. 2 to 0°, filter (cross�
over) pos. 3 to approx. 80 Hz. Switch on the device and
select a musical piece with distinctive bass playback.
Increase the volume of your stereo system to the desired
volume level. Now slowly increase the gain control 1
until you can hear a clear amplification of the bass level.
Next, use the crossover control 3 to select a filter setting
that provides a well�contoured bass. You may have to
alternately optimise the gain control setting 1 and the
filter setting 3.
A droning bass with excessive volume requires a filter
setting with a low frequency.
The phase switch must be set so that the bass is integrated
