Setup and Installation
Proper installation is crucial for optimal performance. It is recommended to have professional installation if you are unfamiliar with car audio wiring.
- Mounting Location: Choose a suitable location in your vehicle that allows for clear sound projection and secure mounting. The tweeters are designed for flush or surface mounting. Ensure there is enough depth behind the mounting surface for the tweeter body.
- Wiring: Connect the provided wiring harnesses to the tweeters. Observe correct polarity (positive to positive, negative to negative) to avoid phase issues.
- Crossover Network: The SPT.06 tweeters include an in-line crossover network. This component filters out lower frequencies, protecting the tweeters from damage and ensuring they only reproduce the intended high-frequency range. Connect the crossover network according to the wiring diagram provided with the product.
- Power Connection: Connect the tweeter system to your car's audio amplifier or head unit. Ensure the power supply is 12V DC.
- Testing: Before finalizing the installation, test the audio system at a low volume to confirm all connections are correct and the tweeters are functioning as expected.

Operating Instructions
Once installed, the Soundstream SPT.06 tweeters operate as part of your car's audio system. Follow these general guidelines:
- Volume Control: Adjust the volume of your car audio system to a comfortable listening level. Avoid excessively high volumes that can lead to distortion and potential damage to the tweeters or your hearing.
- Equalization: Use your head unit's equalizer settings to fine-tune the sound. Tweeters are responsible for high frequencies, so adjust the treble settings to your preference. Avoid boosting treble excessively, which can introduce harshness.
- Amplifier Settings: If using an external amplifier, ensure its gain settings are properly matched to your head unit's output to prevent clipping and distortion.
Maintenance
To maintain the performance and appearance of your Soundstream SPT.06 tweeters:
- Cleaning: Gently wipe the tweeter grilles and housing with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Protection: Keep the tweeters free from dust, debris, and moisture. While the product is robust, it is not water-resistant.
- Inspection: Periodically check the wiring connections to ensure they are secure and free from corrosion.
Troubleshooting
If you encounter issues with your Soundstream SPT.06 tweeters, consider the following:
- No Sound:
- Check all wiring connections for looseness or incorrect polarity.
- Verify that the audio source (head unit, amplifier) is powered on and functioning.
- Ensure the in-line crossover network is correctly installed and not damaged.
- Distorted Sound:
- Reduce the volume level of your audio system.
- Check amplifier gain settings to ensure they are not set too high, causing clipping.
- Adjust equalizer settings to reduce excessive treble boost.
- Inspect the tweeter cone for any visible damage.
- Intermittent Sound:
- Examine wiring for loose connections or frayed wires.
- Check for any short circuits in the wiring.
