Recycle and Disposal
Disconnect the negative terminal of the
battery. Refer to the safety notes of vehicle
manufacturer.
Ensure positions of the holes are nowhere
near the vehicle component to avoid any
damage during drilling.
Incorrect installation may result in malfunc-
tion of the device or the car sound system.
Select a dry and well-ventilated location to
install the device.
The device must not be installed on the rear
shelf, rear seats or exposed locations.
The installation location must be suitable for
screw holes and have stable ground support.
The integrated fuse in the device protects
the output voltage and the entire electrical
system in case of malfunction. Do not replace
damaged fuse with higher current.
This device will automatically turn on if audio
signal is detected. The device will also auto-
matically turn o if audio signal is received.
Please dispose responsibly.

1. Power Indicator
2. Gain Adjustment
3. Low Pass Filter Adjustment
4. Phase Selector
Set the GAIN to 200mV (Min), PHASE to
NORM., LOW PASS FILTER to Center before
turning on the device.
Set the Bass/Treble of head unit to zero. Set
volume to lower level.
Gradually increase GAIN until the desired
sound eect is achieved or until the sound
distribution in the vehicle is even.
Avoid setting volume of the head unit and
GAIN too high to prevent sound distortion.
Ensure speakers are functioning well to avoid
sound distortion too. Then adjust the LOW
PASS FILTER (L.P.F.) to the desired frequency.
Changing the LPF will change the sound
output of the subwoofer. Continue to adjust
GAIN, LPF and volume until the desired
setting is found.
Play the music from the head unit while
sitting at the driver and switch between
NORM and REV to select the desired sound
output setting. The ideal PHASE is subjective
and varies from one vehicle to another,
depending on the location of the device and
the acoustic characteristics of the vehicle
interior.
In no event shall Blaupunkt be liable for any
direct, indirect, punitive, incidental, special
consequential damages, to property or life,
improper storage, whatsoever arising out of
or connected with the use or misuse of our

Examine if your wiring is similar to wiring Diagram 1 or Diagram 2 in case of device operation or
performance failure. The following table indicate other possible problems and solutions. Refer to
an authorized Blaupunkt dealer if problem persist.
Solution
Examine if the ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if battery power is connected correctly to the + terminal.
Ensure supplied voltage is minimum 12V.
Examine if fuse is broken and replace if necessary.
Restart the device if protection LED light is on.
Examine fuses and replace if necessary.
Examine ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if RCA audio cables are connected to the right inputs.
Examine if speaker wiring is intact.
Reset Level Control
Examine the Crossover Control setting.
Observe if the device is still producing noise after turning on and o the
amplier. If yes, examine if the cables are correctly connected and if the
cables and radio are in good condition. Repair or replace if the cables or the
radio are not in good condition.
Ensure RCA connections are properly connected.
Ensure input level of the device matches the signal level of the head unit.
Always set the input level to the lowest.
Examine if crossover frequency is set correctly.
Examine if speaker wire had short-circuit.
Examine the minimum speaker impedance for the amp models is correct.
Ensure good air ventilation around the device. Add external cooling fan if
necessary.
Usually caused by poor RCA cable quality, which release noise. Use only the
best quality cables, and route them away from power cables.
Examine if RCA cable are nowhere near or attached to the vehicle chassis.
Examine if head unit is properly connected to the wires.
