AA-9.0 TFHE
Manual size : 150 x 210mm
Installation
In case you install the amplifiers by yourself, please read owners' manual very carefully.
Before you start your installation, please take all steps into consideration.
If in doubt, please contact with authorized distributors / dealers to check installation and turn in your
car audio systems.
Mounting Preparation
Disconnect the negative (-) battery cable before mounting or making any connections.
Check the battery and alternator ground (-) connections. Make sure they are properly connected
and free of corrosion. Before selecting a mounting location for the amplifiers, please take cooling and
safety into consideration.
Avoid areas such as speaker boxes with excessive vibration !
The amplifiers have been designed with a good heat dissipation heatsink.
In order to avoid excessive heat from the amplifier, it is recommended to find a mounting location
that allows for vertical positioning of the heatsink fins.
For safety purposes, install the amplifier in a dry and well ventilated location and make sure no cables
or other harness of the car is interfaced with the mounting location or will present a hazard to the car’s
cable, control cables, fuel lines/tanks, hydraulic lines or other components of the vehicle.
+12V(B+), GND, REM CONNECTION
+12V / B+ (POWER CONNECTION)
Before mounting the amplifiers, disconnect the negative (-) wire from the battery to protect any accidental
damage to the amplifiers or the audio systems. The amplifiers are equipped with 0 AWG or 4 AWG power
and ground terminals. Connect the power cables to power terminal labeled as + 12V.
Some of the amplifiers are not equipped with fuses, so external fuses are required.
Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the
positive battery terminal within 20 cm of the same cable.
This fuse location will protect the system and the vehicle against the possibility of a short circuit
in the power cable.
Make sure that the fuses and the fuse holder are adequate for the desired application.
GND (GROUND CONNECTION)
Locate a secure grounding connection as close as possible to the amplifier.
Make sure the location is clean and provides a direct electrical connection to the chassis of the vehicle.
Connect one end of an equal sized cable as the positive cable to the location of ground.
It is important that the ground cable is as short as possible, but no longer than 75 cm at maximum.
Run one end of the cable to the grounding point.
Run the other end of the cable to the mounting location.
Connect the ground cable to the terminal labeled as GND.
REM (REMOTE CONNECTION)
Run a remote turn on cable from the switched + 12V source.
This may be a toggle switch, a relay, the source unit's remote ouput cable or power antenna trigger cable.
Connect the remote turn on cable to the power terminal labeled as REM.

PT Link
If you link two same amplifiers as master and slave connection, then connect the 2 amplifies using
the PT Link cable provided. In case when the master unit enters into protection, the slave unit will also
enter into protection thereby protecting the slave unit from unexpected damage.
CAUTION
Before attempting to make any connections to power supply, input and output connectors,
make sure the amplifier is in OFF state. Check polarity of cables carefully as using reversed
polarity will cause damage to amplifier. And to prevent power loss and overheating of wiring,
always use the recommended wire gauges.
CAUTION
Installation of the amplifier should be done in the following steps:
1. Ensure that the ground is appropriate, then connect it to the amplifier.
2. Next step is to connect the +12V wire. Ensure all power terminals are used.
This cable has to be fused at the battery for safety precautions.
3. The final step is connecting the switched remote.

CAUTION
Keep GROUND of equal length. This drawing is for illustration purpose only.
We recommend using 12 AWG speaker cables to obtain intended performance.
Run 12 AWG speaker cables from your speakers to the amplifier’s mounting location
Keep the speaker cables separate from the power cables and and the amplifier’s input cables.
Use grommets where the cables have to penetrate the vehicle chassis.
Connect the speaker wires according to the terminals on each speaker.
Strip 1cm, 3/8" of insulation of the end of each cable and twist the cables strands together tightly.
Make sure there are no stray strands that might touch other cables or terminals and cause short circuit.
Connect the cable ends to the amplifier as shown in the speaker wiring diagram.

Troubleshooting
Assure that the Power LED is on, if so please proceed with step # 3, if not, continue with the steps below;
1. Check the in line fuse (s) on the battery’s positive cable, replace if needed.
2. Assure that the Ground is properly attached to the vehichle’s chassis on a clean metal point, tighten or
grind the connection point once again.
3. Our amplifiers have a high voltage protection. Make sure that the operating voltage is between 8.5V~
16V and voltages above this range will cause the amplifier to go into protect.
Protect LED is on
1. The Protect LED will come on due to the possible circumstances;
a) The impedance connected is under the specified load.
b) Thermal (Overheat), allow for a more suitable mounting as recommened in the install section.
Thermal may also appear if the impedance is under the specified or the voltage is inadequate.
c) Short circuitry, voltage and DC offset.
- Short circuitry, go through all cables including speaker wires, GND, battery’s positive cable.
Voltage, please check step # 3, for DC offset, make sure that a voltage of no more than 4V is
available. Remove the RCA from the input and check whether the amplifier comes out of
protect. If so, check if the output from the Head unit has a DC of 4V, replace / repair if needed.
Audio output (no sound)
1. Assure that RCA connections from the Head unit and the amplifier is properly connected.
Check the entire cable for damages or its like. Test the RCA inputs for DC volts with the source unit on,
replace / repair if needed.
2. Check the routing of the cables, fuses and verify that all connections are connected accordingly.
3. Check whether the speakers are functional.
Turn on thump
1. Disconnect the signal input to the amplifier, then turn it on and off.
a) If the noise is cancelled, then connect a delay turn on module on the REM wire running from
the source unit to the amplifier.
b) Use another 12V source for REM lead to the amplifier. If the noise is cancelled, use a relay
to isolate the amplifier from the turn on thump.
Poor bass response
1. Check that the polarity of the speaker cables are correct. Speakers connected in anti-phase will
cancellate each other, thus the bass response will be absent.
Engine noise
1. Ensure that all signal transferring wires (RCA, speaker cables etc) are kept seperately / away from
the power and the ground wires.
2. Bypass all electrical components between the Head unit and the amplifier.
Connect the Head unit directly to the amplifier’s input. If the noise is eliminated, the unit bypassed
is the one causing the noise.
3. Remove the existing ground wires for all electrical components installed. Ensure that the point of
ground is 100% metal which has been grinded free of rust, paint etc.
4. Replace the ground cable from the OEM battery / alternator and ensure it is grounded accordingly.
5. Test the battery and alternator load (can be carried out by a professional).
Ensure that the vehichle’s electrical system is in a good condition, this includes distributor,
spark plugs / wires, volteage regulators etc.
