TROUBLESHOOTING
NO POWER
Use a multimeter to measure the voltage on the +12V terminal and the remote signal termi-
nal. Use a multimeter to make sure that you have a negative ground connection. Check the
built-in fuse (if there’s one) on the amplifier. If there’s no power coming through – Control
the power cable’s fuse, if it is intact - make a full check of the wiring to ensure cable integ-
rity. When all of the above has been tested/looked over, and all is as it should be but there’s
still no power coming through to the amplifier, consult your local GAS AUDIO POWER dealer.
UNWANTED NOISE
Check your negative grounding point and make sure that the surface is clean (consult the
HOW TO instructions). Make sure that your signal cables or speaker cables are not too close
to the power cables. Look over your wiring so there’s no damage or connection issue.
DISTORTION
Check the speaker cables to make sure that the polarity isn’t reversed on one channel.
Check the settings on the amplifier, make sure that the level/gain is set according to the
instructions. Lower/turn off bass EQ function on the amplifier if used. Check subwoofers.
NO SOUND
Check your head unit to make sure no settings are limiting the amplifier functions. Check all
signal cables. Check all speaker cables. Check all speakers. When all of the above has been
tested/looked over, and all is as it should be but there’s still no sound, consult your local GAS
AUDIO POWER dealer.
PROTECTION
Check all speakers and make sure that no leads or voice coils are damaged. Make sure all
connections are made as they should be and that no leads touch the amplifier chassis.
The amplifier will go into protection if it’s overheated. As soon as the normal operating
temperature is back it will automatically turn back on. To prevent the amplifier from
overheating, make sure to follow the HOW TO installation instructions and leave enough
space around the amplifier so that the airflow is optimized.
The protection mode is activated if the impedance load’s lower than the amplifier limita -
tions. If the input voltage is lower or higher than the amplifier limited range the amplifier will
go into protection. When all of the above has been tested/looked over, and all is as it should
be but the amplifier is still in protection mode, consult your local GAS AUDIO POWER dealer.
