OWNER’S MANUAL

Thank you for purchasing a GAS PRO series high audio performance amplifier.
GAS PRO series amplifiers are using the latest technology design. This
series of amplifiers contains Class D\Class AB architecture that significantly
improves efficiency Timbre is exquisite delicate, ,lowers heat output and
current draw. Don't be fooled by the small size.Class D amplifiers make more
power for There size then traditional designs making installation a breeze
without compromising storage space.
If you do not have experience with automotive electronic and mechanical
systems contact a professional installer. Paying a qualified installer is almost
always cheaper th n paying a dealership to repair your car.a

Running Cables
Carefully run the power and signal cables through the passenger compartment
of the vehicle. Always use a rubber grommet to prevent the power wire from
shorting and to reduce the risk of fire. Depending on which of the GAS PRO
amplifiers you are connecting, use the right size of power and ground wires.
We recommend a fuse to be installed on the power wire within 30-40cm of the
battery for safety.

There is no correct gain setting. Because speakers
require different power demands to reach the same
output, the gains most often need to be used to
compensate for these differences. If you tried to set
all the gains at half way you would probably find the
system didn't sound very good. Using good
judgment and listening carefully to each speaker is
still the best way to tune a system.

1. Before you start, disconnect the negative cable from the car battery. Tape
up the end so it is isolated form the battery.
2. Run an appropriate gauge wire from the battery to the amplifier. Plan this
part of the installation carefully. This cable will carry very high current. If it
should short to the body and it is not properly fused it could catch fire.
3.
.
Connect the power wire to the battery using a fuse capable of the total
urrent load of all amplifiers connected. Don´t install the fuse yet. Wait
until the end of the installation. Locate the fuse as close as possible to the
battery. If the fuse is further that 45cm (wire length) from the battery you
should re-evaluate the wire and fuse location
c
4. Find the closest clear metal area to the amp for a ground. Sand, grind or
scrape all paint and undercoating from the body and screw the ground
securely in place.
5. Run the speaker wire to the speakers. It is advised that you leave some
extra wire at this point. You can ''clean it up'' .later
6. If you have already done so, mount the amp now.
7. Connect the power and ground to the amplifier.
.
8. Connect the remote wire from the head unit to the amplifier. Now is a good
time to turn on the amp for the first time. Make sure it turns on properly and
does not go into protection.
9. Connect the speaker wires to the amp and speakers (make sure the amp is
off first). Make sure the polarity (+ and-) is correct.

10. Connect the RCA to the amp.cables
11. Double check the amplifier controls at this time. Make sure everything is
set correctly for your system.
12. Now you're ready to play it for the first time. It is best to leave the gain all
the way down at first. Start with the head unit volume low and work your
way up.
13. Now you can tune the amp. Take your time and make only one adjustment
at a time. It may take some time to get the system fully adjusted. During
this time the amp is drawing current from the battery. You should check
the battery voltage from time to time and re-charge it if it gets low. That's it.
You're done. Now have fun.

Before removing your amplifier, refer to the list below and follow the
suggested procedures Always test the speakers and their wires first.
Check for good ground connection
Check that remote DC terminal has at least 8 5Vdc
Check that there is battery power on the terminal
Check all fuses
Check that protection LED is not lit If it is lit shut off amplifier briefly and
then power it

Disconnect all RCA inputs to the amplifier. If hiss/noise disappear, then plug
in the component driving the amplifier and unplug its input. If hiss/noise
disappears, go on until the faulty/noise component is found. It is best to set
the amplifier input level as insensitive as possible. The best subjective signal
to noise ratio is obtained this way. Try to derive as high signal from the head
unit as possible.
Check that the level control is set to match the signal level of the head unit.
Check that all crossover frequencies have been properly set.
Check after short circuit on the speaker leads.
Check after short circuit on the signal cables.
