PIAA Oto Bass Horns

PIAA oto-style bass horns deliver a strong, attention-grabbing warning signal. They're engineered to produce a powerful 112 dB output, combining rich low-frequency tones for a deep, distinctive sound that stands out in busy traffic. The horns have a thin spiral/trumpet design that allows for easy installation; while also featuring a durable construction that helps to ensure long-lasting performance in a variety of weather environments.

Additional details:

* Slim, lightweight aftermarket replacement for weak factory car or motorcycle horns
* Bold, commanding sound is ideal for high visibility, road presence, and enhanced safety
* Typically operates on a dual-frequency range—such as 390Hz (low note) and 430Hz (high note)—to deliver a rich, resonant bass tone (distinct from standard higher-pitch or sports horns)
* Operates on standard 12 V vehicle electrical systems and usually utilizes existing vehicle wiring or plug-and-play connectors without needing complex relays
