Resolution
- Visually inspect the speaker for deterioration or holes.
- Reduce the output level of the source.
- Verify that the negative and positive speaker wires from the speaker are securely connected to the terminals on the amplifier.
- Verify that there are no missing screws. Replace all screws that you removed during installation.
- Have an authorized dealer complete an audio test (for example, pink noise,
- Frequency sweeps, content, and program material.
There is speaker noise or his.s
The speaker is producing static noise or hiss when powered.
Resolution
