STATUS LED
This bi-color LED glows green when power is
on and no problems are present. If one of the
protection circuits comes on, it will change to
red.
SHIFT
Use this switch to help compensate for time
alignment problems in the system. Such
problems usually result from having the
subwoofer at a different distance from the
listener than the other speakers in the system.
POWER ON
T
he AUTO POWER ON(ON/OFF) is for high
level (speaker-level) connections. When the
switch is in the “ON” position, the subwoofer
AUTO POWER ON when there is signal input.
If the amplifier detected no signal input, the
amplifier will auto turn off. If you prefer to use
the remote turn on/off connection, the switch is
in the OFF position.
Note: Please connect the remote terminal
to the remote output of head unit as
Fig.4. When you hear the unit turn ON/OFF
POP noise from the subwoofer.
GAIN CONTROL
After you have installed your system, turn this
control to minimum.
Turn the head unit on (and the subwoofer will
turn on via the remote connection). Turn the
head unit volume to about 2/3 full level.
Slowly turn up the subwoofer input gain control
until you hear a small amount of distortion. Then
reduce the level until the distortion is completely
gone. Level the control at this setting.
LEVEL CONTROL PORT
Attach the included remote level control to
control the volume level of the subwooer
independently.
LEVEL (speaker level) INPUTS
If your head unit does not have RCA outputs
you can use the speaker outputs for the audio
source for the subwoofer. Use the supplied
cable and wire harness and connect the
outputs properly as shown in the connection
diagram in this manual.
LEVEL RCA INPUTS
Low level inputs are the recommended way
to introduce the audio signal to the subwoofer
if RCA outputs are present on your head unit
or other signal source (such as a sound
processor).
PASS FILTER
T
his control permits you define the frequency
range you want the subwoofer amplifier to
receive. The subwoofer will reproduce all sound
BELOW the frequency you set.
Note: The low pass filter frequency can be
higher or lower than the
have +/-20% tolerance.
Do not use a fuse with a different value
and NEVER replace the fuse with a wire
or coin.
INPUT TERMINAL
BOOST
The BASS BOOST feature will increase the
sound level in the bass frequencies.

Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk
or hatchback installations will require a 15-20 feet RCA cable, while pickup trucks
and under-seat installations will require a 6-12 feet RCA cable. Always use a
high quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!

To Audio outputs of head
unit or signal processor
High Level Input Wiring
T
he high level input(s) should only be used when your receiver lacks RCA outputs.
If the RCA outputs are not present, connect the speaker outputs from the receiver
to the high level input connector of the amplifier. Be sure to observe polarity to
avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!

Power Connections
Connect the ground terminal to the closest point on the chassis of the vehicle.
Keep this ground wire to less than 39" (100 cm) in length. Use 8 gauge
(or heavier) wire.
Connect the remote terminal to the remote output of head unit using 16 gauge
( or heavier ) wire.
Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 8 gauge
(or heavier) cable from this fuse to the amplifier location. Then connect the fuse
holder to the "BATT+" (+12V) connection on the subwoofer rear panel.

Troubleshooting
If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
SYMPTOM
Amplifier will not
power up.
POSSIBLE REMEDY
Check to make sure you have a good ground connection.
Check that the Remote Input (Turn-On) has at least 5VDC.
Check that there is battery power on the (+) terminal.
Check that there is at least 12v.
Check all fuse, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then repower it.
Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving.
Remote speaker leads, and reset the amplifier. If the Protection LED still
comes on, then the amplifier is faulty and needs servicing.
Check that all fuses are OK.
Check that unit is properly grounded.
Check that the Remote Input (Turn-On) has at least 5VDC.
Check that the RCA audio cables are plugged into the proper inputs.
Check all speaker wiring.
Reset the Level Control.
Check the Crossover Control settings.
Disconnect all RCA inputs to the power sub's control panel. If the hiss
disappears, then plug in the component driving the amplifier and unplug
its inputs. If the hiss disappears at this point, go on until the faulty/noisy
component is found.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to
set the head unit as high as possible (without distortion) and the amp
input level as low as possible.
Check for improperly grounded RCA interconnects.
Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Check that the minimum speaker impedance for the amp model is correct.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add and external cooling fan.

故障排除
故障现象故障原因
1.检查功放电源地线是否连接良好。
2.检查电瓶正极电压是否加在功放的电源端子正极。
3.检查REMOTE电压不要低于5VDC。
4.检查电源端子正极电压不要低于+12V。
5.检查保险丝是否损坏（开路）。
6.确认保护指示灯是否亮起，如指示灯亮起则重新起动功放。
1.检查喇叭接线端子是否短路。
2.调低音量电位器以防止过载保护。
3.卸掉喇叭连接线，重新起动功放，如保护指示灯亮则功放已损坏，需要维修。
1.检查保险丝是否损坏（开路）。
2.功放是否正确接地。
3.功放启动电压不要低于5VDC。
4.检查RCA音频线或高电平输入线是否正确连接到功放。
5.检查喇叭线是否连接良好。
1.重新设定音量电位器。
2.检查虑波器电位器是否在正确的位置。
1.断开功放的信号输入线，如果嘶嘶声消失就是信号源有问题，此时要确认信号线是否
连接良好或信号线质量是否有问题，否则主机可能有问题。
2.尽可能把功放音量电位器开小，同时尽可能把主机音量开大（不要失真）。
1.检查RCA的地线是否连接好。
1.检查功放音量电位器是否太大了，功放音量电位器要配合好主机音量。
2.检查虑波器电位器大小是否合适。
1.检查喇叭阻抗是否低于功放的标示阻抗。
2.检查功放的安装位置是否通风良好。
1.主要是RCA信号线质量太差的原因，要换用质量好的RCA信号线，并要远离电源线。
1.检查RCA信号线地线不能连接到汽车底盘。
