Troubleshooting
9
In the event that your Audiobahn speakers appear to require service we ask that you
first do a little troubleshooting to determine if the problem is actually the speaker, or a
problem located in a different part of the vehicle such as the amplifier, wiring, fusing or
possibly the source unit.
If your Audiobahn speakers have been installed professionally by an authorized Audio-
bahn Dealer, we recommend that you return to the dealer and demonstrate the problem
to a qualified installer or repair technician. If you installed the speaker yourself, use the
following guidelines to help find the problem.
1) No Sound
*Check the source or amplifier for power and be sure they are operating properly
*Check all signal connections
*Check for any wiring that may be shorting together or touching the metal chassis
*Check all ground connections
2) Distorted Sound at All Volumes
*Check for bad speaker connections
*Check wiring for correct polarity
3) Distorted Sound at High Volumes Only
*Check for loose mounting of the speaker
*Check the woofer cone for any damage or defects
*Inspect the speaker for debris in the cone or other obstructions
4) Poor Bass Response
*Check wiring for correct polarity
*Check for unstable or loose mounting surface
*Check bass & treble controls at the source unit or amplifier
5) Poor High Frequency Response
*Check wiring for correct polarity
