4. Setup and Installation
Proper installation is crucial for optimal performance and longevity of your speakers. If you are unsure about any steps, it is recommended to seek professional installation.
Safety Precautions:
- Disconnect the vehicle's battery before starting any electrical work.
- Ensure all wiring is properly insulated to prevent short circuits.
- Wear appropriate safety gear, including eye protection.
Installation Steps:
- Choose Mounting Location: Select a suitable flush-mount location in your vehicle that accommodates the 6.5-inch speaker size.
- Prepare Mounting Surface: Carefully cut the mounting hole to the correct diameter. Ensure there is sufficient depth for the speaker magnet.
- Wiring: Connect the speaker wires to your amplifier or head unit. Ensure correct polarity (positive to positive, negative to negative) to avoid phase issues. The SME.650 has a 4 Ohm impedance.
- Secure Speaker: Place the speaker into the mounting hole and secure it using the provided mounting hardware. Do not overtighten the screws.
- Test System: Reconnect the vehicle's battery and test the audio system at a low volume. Gradually increase the volume to check for proper operation and sound quality.

5. Operating Instructions
Once installed, operating your Soundstream SME.650 speakers is straightforward. Follow these guidelines for the best audio experience:
- Volume Control: Adjust the volume on your head unit or amplifier to a comfortable listening level. Avoid excessively high volumes that can lead to distortion or speaker damage.
- Equalizer Settings: Experiment with your audio system's equalizer settings to fine-tune the sound to your preference. Since these are mid-range speakers, focus on enhancing the mid-frequency bands.
- Avoid Clipping: If you hear any distortion, reduce the volume immediately. Clipping (a form of distortion) can damage your speakers and amplifier.
6. Maintenance
Regular maintenance helps prolong the life and performance of your speakers:
- Cleaning: Gently wipe the speaker cones and surrounds with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check the speaker wiring for any signs of wear, fraying, or loose connections. Ensure mounting screws remain secure.
- Environmental Factors: While designed for car environments, avoid exposing speakers to extreme temperatures or direct moisture if possible, as they are not waterproof.
7. Troubleshooting
If you encounter issues with your Soundstream SME.650 speakers, try these troubleshooting steps:
- No Sound:
- Check all wiring connections at the speaker, amplifier, and head unit.
- Ensure the amplifier is powered on and receiving a signal.
- Verify the head unit's volume and source settings.
- Distorted Sound:
- Reduce the volume on your head unit or amplifier.
- Check for loose wiring connections or frayed wires.
