Product Information
Full details
The PIAA Superior Bass Horn is designed for drivers seeking a significant safety upgrade over factory-installed horns, providing a deep, resonant, and attention-grabbing sound profile. It is best suited for daily commuters and road-trip enthusiasts who require a more authoritative audible alert to navigate heavy traffic, though users should be aware that its 112dB volume is substantially louder than stock options and may require additional space for mounting during installation.

FAQs
Is the PIAA Superior Bass Horn street legal?
In most jurisdictions, yes, as it serves as a safety warning device. However, always check your local laws regarding decibel limits for vehicle horns.
Do I need a separate relay to install this?
It is highly recommended, especially if your vehicle's stock wiring is thin, to ensure the horns receive consistent power and do not overload the factory switch.
Can I install just one of the two horns?
The kit is designed to work as a dual-tone system for the specific bass sound profile; installing only one will change the pitch and volume effectiveness.
Is this horn compatible with motorcycles?
Yes, provided there is enough physical space to mount the units and your motorcycle's electrical system can support the draw.
What is the difference between 330Hz and 400Hz?
These represent the frequency of the sound waves. Using both together creates a harmonized, deep, and 'superior' bass sound compared to a single-frequency horn.
Troubleshooting
Horn produces a weak or distorted sound.
Check the ground connection to ensure it is attached to a clean, unpainted metal surface on the chassis.
The horn does not sound at all when the button is pressed.
Check the vehicle's fuse box to ensure the horn fuse has not blown; if the fuse is intact, use a multimeter to verify that 12V power is reaching the horn terminals.

Setup, Compatibility & Care
Installation of the PIAA Superior Bass Horn involves removing the factory horn and mounting the PIAA units in a location protected from direct water spray. While the unit is weather-resistant, mounting it so the opening faces downward prevents water collection within the horn housing.
Before installation, ensure your vehicle's current wiring is capable of handling the amperage of a dual-horn system; if the factory horn circuit is fused below 15A, a separate relay harness is highly recommended. To maintain the horn, periodically check that the mounting bolts remain tight, as engine vibrations can loosen hardware over time. No lubrication or internal maintenance is required.
