What Causes the Weak Sound of Car Tweeters?
2 Answers
About the reasons for the weak sound of car tweeters, the following explanations are provided: 1. The weak sound of tweeters may be caused by the lack of a crossover capacitor. In this case, a crossover capacitor can be installed to improve the sound. When installing tweeters, it is essential to go to a professional institution for the work and purchase reliable products. If you have high requirements for sound quality and the tweeters in high-configuration models offer better sound quality and are from well-known brands, it is recommended to directly choose the high-configuration model. 2. After modifying the tweeters, you can opt for full-vehicle sound insulation. When performing full-vehicle sound insulation, it is also crucial to go to a professional institution and use high-quality sound insulation materials. Additionally, be careful not to damage the original vehicle wiring during the installation of the tweeters.
A while ago, while tinkering with my car audio system, I encountered an issue where the tweeter volume became noticeably weaker. After troubleshooting, I identified three common causes: First, the aftermarket speakers were of poor quality—those cheap metal-diaphragm ones bought online for a few dozen bucks tend to vibrate abnormally when damp. Second, door panel resonance interference, especially in modified cars without added soundproofing foam, can absorb high-frequency energy while driving. The trickiest issue was the head unit’s output problem—testing with a multimeter revealed that an amplifier module bought from Taobao only delivered 2V output, far below the standard 4V. My advice: first check for oxidized (greenish) wire connectors, then test with a pair of branded used speakers, and finally consider adding a DSP for tuning. Remember, reversing the crossover can also lead to insufficient sound pressure.
