Before Troubleshooting

Before Troubleshooting
Problems with the audio system can be caused by factors such as wrong operation and outside noises. Eliminate these causes before troubleshooting.

Causes of noise
1. Defective audio system or improper installation
2. Noise from multi path or neon signs (ambient noise)
3. Vehicle-induced noise





Because ambient noise is only a temporary occurrence, this section deals only with vehicle-induced noises.





FM multipath
FM waves can cause a problem called multipath receiving. This happens when the radio picks up a direct wave and a reflected wave at the same time, which results in a "Dead Spot" or distorted sound.
