TROUBLESHOOTING
NO POWER/SOUND
Start by looking over the active subwoofer to make sure it isn’t damaged. If your active
subwoofer doesn’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 on the active subwoofer’s amplifier. If there’s no power
coming through – control the fuse on the power cable. If this is 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 active subwoofer. 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.
DISTORTION
Start by looking over the active subwoofer and other 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 subwoofer’s
amplifier, make sure that the gain is set according to the amplifier’s instructions. Lower the
effetcs of the slim subwoofer amplifier’s Bass BOOST settings, or turn it off.
UNWANTED NOISE
Start by looking over the active subwoofer and other 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
