TROUBLESHOOTING
NO POWER/SOUND
Check the enclosure/speakers to make sure it isn’t damaged. If not all speakers are playing,
make sure the AST connector is in place, or check cross over settings for both amplifiers. If
your pre-loaded enclosure 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. Make sure that you have a negative ground connec-
tion. Check the built-in fuse (if there is one) on the amplifier. If there’s no power coming
through – control the fuse on the power cable. If the fuse is intact you should check all of the
wiring to ensure cable integrity.
DISTORTION
Start by looking over the enclosure/speakers 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 function is set
according to the amplifier’s instructions. If your amplifier has a boost function, lower its
effect or turn it off.
When all of the above has been tested/looked over, and all is as it should be but the pre-
loaded enclosure still has no power/sound or other problems, consult your local GAS AUDIO
POWER dealer/installer
