Setup and Installation

Proper installation is crucial for the performance and longevity of your tweeters. It is recommended to have this installation performed by a qualified professional.

Mounting

The SPT.20 tweeters are designed for flush mounting. Choose a mounting location that provides optimal sound dispersion and does not obstruct vehicle operation or safety features. Common locations include door panels, A-pillars, or dashboard. Ensure there is sufficient depth behind the mounting surface for the tweeter body.

Carefully mark the desired mounting location.
Cut an appropriate size hole using a hole saw or similar tool, ensuring a snug fit for the tweeter body. Refer to the specifications section for exact dimensions.
Secure the tweeter in place using the provided mounting hardware.

Wiring

The SPT.20 tweeters have a 4-ohm impedance. They should be connected to an appropriate amplifier channel, typically through a passive crossover network (not included) or an active crossover from your head unit or amplifier. Always ensure correct polarity (+ to + and - to -) to prevent phase issues and ensure optimal sound quality.

Connect the positive (+) terminal of the tweeter to the positive output of your amplifier/crossover.
Connect the negative (-) terminal of the tweeter to the negative output of your amplifier/crossover.
Use appropriate gauge wiring for your installation to minimize power loss and ensure stable connections.

Operating Instructions

Once properly installed and connected, the Soundstream SPT.20 tweeters will function as part of your car's audio system. They are designed to reproduce high-frequency audio signals (treble).

System Power On: Turn on your car's audio system.
Audio Playback: Play audio through your head unit. The tweeters will reproduce the high-frequency components of the sound.
Volume Adjustment: Adjust the volume through your head unit or amplifier. Avoid excessively high volumes that cause distortion, as this can damage the tweeters.
Sound Customization: Use your head unit's or amplifier's equalizer and crossover settings to fine-tune the sound to your preference. Ensure the tweeters are receiving a high-pass filtered signal to prevent damage from low frequencies.

Maintenance

The Soundstream SPT.20 tweeters require minimal maintenance to ensure long-lasting performance.

Cleaning: Gently wipe the tweeter surface with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
Inspection: Periodically check wiring connections to ensure they are secure and free from corrosion.
Environmental Protection: Avoid exposing the tweeters to direct sunlight for extended periods or extreme temperatures, which can degrade materials over time.

Troubleshooting

If you experience issues with your Soundstream SPT.20 tweeters, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
No sound from tweeters	Loose or incorrect wiring connection Blown fuse in amplifier or head unit Amplifier or head unit not powered on Crossover settings incorrect (e.g., high-pass filter too high or off) Damaged tweeter	Check all wiring connections for proper polarity and secure fit. Inspect fuses in your audio system components. Ensure all audio components are powered on. Verify crossover settings are appropriate for tweeters (typically 2kHz or higher). If all else fails, the tweeter may be damaged and require replacement.
Distorted or harsh sound	Volume too high, causing clipping Incorrect gain settings on amplifier Tweeter receiving full-range signal (no high-pass filter) Damaged tweeter	Reduce volume to a comfortable level. Adjust amplifier gain settings to match head unit output without distortion. Ensure a high-pass filter is active for the tweeters, preventing low frequencies from reaching them. Inspect tweeter for physical damage.
One tweeter not working	Loose or incorrect wiring for that specific tweeter Damaged tweeter	Check wiring connections for the non-working tweeter. Swap the non-working tweeter with a known good one (if available) to diagnose if the tweeter itself is faulty.
