carefully before operating the device for the rst time.
Safety Notes
Ensure to follow below safety notes during installation
and wiring connection : -
•
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.
Installation and Connection Instructions
•
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.
Intergrated Fuse
•
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.

Remote Control
-
1
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
2
to lower level.
Gradually increase GAIN until the desired sound
3
eect is achieved or until the sound distribution in
the vehicle is even.
Avoid setting volume of the head unit and GAIN too
4
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
5
the subwoofer. Continue to adjust GAIN, LPF and
volume until the desiredsetting is found.
Play the music from the head unit while sitting at the
6
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.
Recycling and Disposal
Do not dispose of your old unit in the
household trash!
Use the return and collection systems
available to dispose of the old device.

Solutions
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 amplier.
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.
