OWNER’S MANUAL
Thank you for pu rchasing a GAS PRO series high audio perform ance amplifier.
GA S PRO s eries amplifiers are using th e la test technology design. T his
se ries of amplifiers contains C lass D\Clas s AB architecture that s ignificantly
im proves efficiency Timbre is exquisite de licate, ,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 d esigns making installation a breeze
without compromising storag e s pace.
Running Cables
Carefully run the po wer and signal cabl es through the pass enger compartm ent
of the vehicle. Always u se a rubber grommet to p revent the powe r w ir e f rom
sh orting and to r educe the risk of fire. Depe nding on which of the GAS PRO
am plifiers yo u are connecting, use the right size of power and ground w ires.
We recommen d a fuse to be i nstalled on the powe r w ire within 30-40c m of th e
ba ttery for safety.
If you do not have experience with automotive electronic and mech anical
systems contact a professional installer. Payi ng a qualified installer is almost
always cheape r th n p aying a dealersh ip to repair your car.a

There i s no corr ect ga in setting. Because speakers
require different p ower demands to reach the same
output, the gains most often need to be used to
compensate for thes e differences. If you tried to set
all the gains at ha lf way you would probably find the
sys tem didn't sou nd very g ood. Us ing goo d
judgment and listening carefully to each speak er is
still the best way to tune a system.

1. Before you start, d isconnect th e ne gative cable from the car battery. Tape
up the end so it is isolated form the battery.
2. Run an appropriate gauge wire from the batt ery to the amplifier. P lan this
part of the installation carefully. This cable will carry very h igh current. If it
should short to the body and it is not properly f used it could catch fire.
8. Connect the remote wire from the head unit to the amplifier. No w is a go od
time to turn on the amp for the first time. Make sure it tu rns o n properly an d
does not go into protection.
9. Connect the speaker wires to the amp and sp eakers (make sure the amp is
off first). Make s ure the polarity (+ and-) is correct.
3..Co nnect the power wire to t he battery using a fuse capable of the to tal
urrent load of all ampl ifiers connected. Don´t install the fuse yet. Wait
c
until the end of the installation. L ocate the fuse as close as po ssible to the
battery. If th e fuse is further th at 45cm (wire leng th) f rom the batter y yo u
sh ould re-eva luate the wire and fuse location
4. Find the closest clear metal area to the amp for a ground. Sand, grin d or
scrape all paint and undercoating from the body and screw the g round
securely in place.
5. Run the speaker wire to the speakers . It is advised that you leave some
extra wire at this point. You ca n ''clean it up'' .later
6. If you have already done so, mount the amp no w.
10. Connect the RCA to the amp.cables
11. Double check the amplifier controls at this time. Make sure everything is
set correctly for y our s ystem.
12. Now you're ready to play it for the first time. It is best to leave the ga in all
the way down at first. Start with the head unit volume low and work your
way u p.
13. Now you can tune the amp. Take your t ime and make only one adju stment
at a time. It may take some time to get the system fully ad justed. During
this time the amp is drawing current from the battery. You shou ld check
the b attery voltage from time to time and re-charg e it if it g ets low. That's it.
You're done . Now h ave fun.
7. Connect the power and ground to the amplifier.

MAKE GROUND CABLE AS
SHORT AS POSSIBLE
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.
