Troubleshooting
If you experience issues with your subwoofer, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | No power to amplifier, incorrect wiring, amplifier in protect mode, incorrect impedance selection. | Check amplifier power and fuses. Verify all wiring connections. Ensure impedance setting matches amplifier. |
| Distorted Sound | Amplifier gain too high, incorrect crossover settings, damaged voice coil. | Reduce amplifier gain. Adjust crossover frequency. Inspect subwoofer for physical damage. |
| Weak Bass | Incorrect impedance, phase issues, insufficient amplifier power, improper enclosure. | Verify impedance setting. Check speaker polarity. Ensure amplifier power matches subwoofer RMS rating. Review enclosure design. |
If the issue persists after attempting these steps, contact Memphis Audio customer support or a qualified car audio technician.
