CONTROL FUNCTIONS
1. SPEAKERS
Connect speakers/subwoofers to these terminals. Be sure to check wire for proper
polarity. Never connect the speaker cables to chassis ground.
2. +12 Volt Power
Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal
of the vehicle battery or the positive terminal of an isolated audio system battery.
Warning: Always protect this power cable by installing a fuse or circuit breaker of the
appropriate size within 18 inches (45cm) of the battery terminal connection.
3.Remote Turn On
This terminal turns on the amplifier when (+)12 volt is applied to it . Connect it to
the remote turn on lead of the head unit or signal source.
4.GND
Connect this cable directly to the frame of the vehicle. Make sure the metal frame
has been stripped of all paint down to the bare metal. Use the shortest distance
possible. It is always a good idea to replace the factory ground at this time with a larger
cable equal to the new amplifier power cable or larger. Connecting to the battery is the
best ground in the vehicle, but typically not practical to run ground that far.

CONTROL FUNCTIONS
5. RCA input jacks
These RCA input jacks are for use with source units that have RCA outputs. A
source unit with a minimum level of 200mV is required for proper operation. The use of
high quality twisted pair cables is recommended to decrease the possibility of radiated
noise entering the system.
6.High level inputs
The high level inputs are for use with speaker level wiring.Some source units do
not have RCA outputs,so use this terminal for speaker level signal input.
CAUTION:Never use high level input when RCA inputs available.
7. Level Control
The level control will match the amplifiers sensitivity to the source units signal
voltage. The Operating range is 200mV minimum to 5V maximum. This is NOT a volume
control!
8.Low Pass Filter Control
This control is used to select the desired low pass x-over frequency. The frequency
can be adjusted from 40Hz to 220Hz for all bass mono models.
9.Subsonic Filter Control
This control can filter out unwanted low frequency from 10Hz (OFF) to 50Hz.This
function will increase the power handling of your woofers.
10.Bsss Boost Level switch
This switch can boost bass level by 0dB, 6dB or 12dB. The boost frequency is
centered at 50Hz.
11. X-over mode and frequency Control (4-ch)
These controls allow control over the frequencies played for the front channels.
There is an option for Low Pass. Full Range or High Pass. In LP or HP mode the frequency
range is from 50Hz to 4kHz.
12. X-over mode and frequency Control (4-ch)
These controls allow control over the frequencies played for the rear channels.
There is an option for Low/BandPass,Full Range or High Pass. In HP mode, the
frequency range is from 15Hz to 500Hz. In LP mode, the frequency range can be
switched from 50Hz to 800Hz. or 250Hz to 4kHz. In the higher range, the LPF can be set
at 4kHz for a middle bass while the front channels are also set at 4kHz for a tweeter
resulting in a 2-way x-over and eliminating the need for a passive x-over. Even with a set
up like this, the middle bass can still be protected by the HPF which is not defeatable. It

INSTALLATION PRECAUTIONS
Before you install the amplifier, investigate your car's layout very carefully. Take
special care when you work near the gas tank, fuel lines, hydraulic lines and electrical
wiring. Before making or breaking power connections in your system, disconnect
the vehicle battery. Confirm that your head unit or other equipment is turned off while
connecting the input jacks and speaker terminals. If you need to replace the power fuse,
replace it only with a fuse identical to that suggested by this manual. Using a fuse of a
different type or rating may result in damage to your audio system or your amplifier
which is not covered by warranty .
MOUNTING AMPLIFIER
1.Plan the installation of the amplifiers and find a suitable location with sufficient air
circulation.
2. Check the drawing below to mount the bottom amplifier.
Fig 5. Mount amplifier
7
CONNECTING THE AMPLIFIER
1.Select cable and fuse according to the following table.
2. Connect the amplifiers ground with 4 gauge or heavier cable to a close, bare metal
part of the frame or chassis. Use a nut and bolt, NOT a screw! The ground cable must be
at least the same size as the +12volt cable.
3. Connect the remote terminal to remote output of the head unit using 16 gauge (or
heavier) wire.
4. Connect the a 100A fuse holder within 18”(45cm) of the car battery, and run 4
gauge or heavier cable from this fuse to the amplifier.
5. Connect all the inputs with high-quality cables.
6. Insert 100A fuse(s) into the battery fuse holder(s).

Check for short circuits on speaker leads.
Check the speaker load not beyond the minimum load.
Remove speaker lead, and reset the amplifier. If the protection LED still
Comes on, then the amplifier is faulty and needs servicing .
No output Check that the RCA audio cables are plugged into the proper inputs.
Check all speakers wiring.
Check the headunit output and the amplifier level setting.
Low output Reset the level Control.
Check the Crossover Control settings.
High hiss in
The speakers
Check the RCA cable is not shorted to power ground at amplifier side.
Check the amplifier grounding.
Distorted sound
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 as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
Very hot
Check that the minimum load impedance for the amplifier model is correct.
Check that there is good air circulation around the amplifier. In some
applications, It may be necessary to add an external cooling fan.

No output Check that the RCA audio cables are plugged into the proper inputs.
Check all speakers wiring.
Check the headunit output and the amplifier level setting.
Low output Reset the level Control.
Check the Crossover Control settings.
High hiss in
The speakers
Check the RCA cable is not shorted to power ground at amplifier side.
Check the amplifier grounding.
Distorted sound
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 as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
Very hot
Check that the minimum load impedance for the amplifier model is correct.
Check that there is good air circulation around the amplifier. In some
applications, It may be necessary to add an external cooling fan.
