3 Installation
Note
Follow all mounting and wiring instructions.•
Mount the amplifier in car
You can mount the amplifier either under a seat
or on the rear tray.
Note
To avoid interference, do not place the•
amplifier too close to the car audio or antenna.
The supplied mounting screws are 25mm long.
•
Make sure that the mounting board is thicker
than 25mm.
1Place the unit on the location for
installation.
2Mark the positions of the four screw
holes.
3Drill the holes with driller of
approximately 4mm in diameter.
4Mount the unit with the supplied screws.

Connect power
1Make the power connection as illustrated
below:
Connect the ground wire from the•
car to the GND socket.
Connect the remote wire from the•
car audio to the REM socket.
With this connection, you can turn•
on/off the amplifier with the car
audio.
Connect the power wire from the•
car battery to the +12V socket.
Connect speakers
Note
Use speakers with an impedance of 2 to 8 ohm•
(4 to 8 ohm when used as a bridged amplifier).
Match the “left”, “right”, “+” and “-” terminals
•
correctly. Revised polarity may degrade sound
quality.

Adjust bass boost
To enjoy more bass sound:
1Set HPF at OFF mode.
2Slide BASS BOOST to 12dB position.
Tip
If• BASS BOOST is set at 0dB position, no
extra bass will be boosted.
Note
If• HPF is set at 180Hz mode, the bass frequency
will be filtered.
About the protector
indicator
The amplifier has a built-in protection circuit to
protect the transistors and speakers in following
conditions:
The amplifier is overheated.•
A DC current is generated in•
speakers.
The battery voltage is too low or too•
high. Or
The speaker terminals are short•
circuited.
When the PROTECTED indicator
lights up in red, the amplifier shuts
down automatically. In this case
please:
1Take out the disc or tape and turn off the
car audio.
2Check the cause of the malfunction.
3If the amplifier is overheated, let it cool
down.
4 Use your power
amplifier
Select HPF/LPF mode
1Slide LPF or HPF to the selected mode.
HPF (high-
pass-filter)
180Hz More low frequency
signal is filtered. Select
this if you prefer less
bass effect.
OFF
LPF (low-
pass-filter)
80Hz More high frequency
signal is filtered. Select
this if you prefer
stronger bass effect.
OFF
Adjust input level
To ensure sound quality, adjust input level to
match it with the car audio’s output voltage.
1Check the line output voltage of the
connected car audio.
2Rotate INPUT LEVEL to select a
matched voltage: 0.3V to 6V.

1Pull out the damaged fuses.
2Replace the fuses with the supplied
fuses or to buy two fuses that match the
current rating of the damaged fuses
(25A x 2).
If the fuse gets damaged immediately after they
are replaced, the amplifier might have internal
malfunction. In such case, consult qualified
personal for repair.
