Buying Guide: Key Purchase Considerations
What should you consider before buying a car horn upgrade? First, check voltage compatibility—most options here are 12V systems. Next, assess loudness in dB: higher dB numbers indicate louder warnings but may be more disruptive in certain areas. Consider the mounting approach: direct replacement units simplify installation, while dual-trumpet kits may require more space but offer a bigger sound.
