TROUBLESHOOTING
NO POWER/SOUND
Check the speakers to make sure they’re not damaged. If your speakers don’t get any power,
the most common issue is either in the wiring or in the amplifier. Use a multimeter to
measure the amplifier’s voltage on the +12V terminal and the remote signal terminal. 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 fuse
on the power cable. If it’s intact - make a full check of the wiring to ensure cable integrity.
Check all the speakers connected to your sound system. Check all the speaker cables and all
the signal cables. Check your head unit to make sure no settings are limiting the amplifier’s
functions or the 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/installer.
UNWANTED NOISE
Start by looking over the speakers in the sound system so there is no damage or connection
issue with the wiring. Make sure that your signal cables or speaker cables aren’t too close to
the power cables. Check your amplifier’s grounding point and make sure that the surface is
clean. When all of the above has been tested/looked over, and the unwanted noise does not
vanish, consult your local GAS AUDIO POWER dealer/installer.
DISTORTION
Start by looking over the speakers in the sound system so there’s no damage or connection
issue with the wiring. 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 gain/level is set
according to the amplifier’s instructions. If your amplifier has a boost function, lower its
effect or turn it off.
