4.2 Wiring Instructions
The PRO-TW220B tweeters come with a built-in capacitor filter, which acts as a basic high-pass crossover. Connect the positive (+) terminal of the tweeter to the positive (+) output of your amplifier or head unit, and the negative (-) terminal of the tweeter to the negative (-) output. Ensure all connections are secure and properly insulated to prevent short circuits.

5. Operating Instructions
Once properly installed and wired, the DS18 PRO-TW220B tweeters will operate as part of your audio system. They are designed to reproduce high frequencies (treble) with clarity and power.
- Power Handling: These tweeters can handle 120 Watts RMS and 240 Watts Max power. Ensure your amplifier's output does not exceed these ratings to prevent damage.
- Impedance: The tweeters have a 4 Ohm impedance. Match this with your amplifier's stable impedance output.
- Sound Adjustment: Use your head unit's or amplifier's equalizer settings to fine-tune the high-frequency output to your preference. Avoid excessive treble boost, which can lead to distortion or damage.
6. Maintenance
The DS18 PRO-TW220B tweeters require minimal maintenance to ensure long-lasting performance.
- Cleaning: Use a soft, dry cloth to gently wipe the surface of the tweeters. Do not use harsh chemicals or abrasive cleaners.
- Inspection: Periodically check wiring connections for looseness or corrosion.
- Environment: While durable, avoid exposing the tweeters to direct water spray or extreme dust, which can affect performance over time.
7. Troubleshooting
If you experience issues with your DS18 PRO-TW220B tweeters, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from tweeters | Loose or incorrect wiring Amplifier not powered on Blown fuse in amplifier/head unit | Check all wiring connections for security and correct polarity. Verify amplifier is receiving power and is turned on. Inspect and replace any blown fuses. |
| Distorted sound | Overpowering the tweeters Incorrect gain settings Poor quality audio source | Reduce volume or amplifier gain. Ensure RMS power matches tweeter rating. Adjust amplifier gain settings appropriately. Try a different audio source to rule out source issues. |
| Intermittent sound | Loose connections Damaged wiring | Secure all wiring connections. Inspect wiring for cuts or fraying and repair/replace as needed. |
