PIAA H09 Dual Tone Horns Kit 330Hz and 400Hz

PIAA HO9 Dual Tone Horn Kit – Deep & Commanding Sound (330Hz + 400Hz)

For drivers who prefer a deep, "full-bodied" resonance over high-pitched frequencies, the PIAA HO9 is the ultimate choice. Featuring the lowest frequency combination in the PIAA lineup (330Hz and 400Hz), this kit produces a commanding, bass-heavy tone typically found in luxury European vehicles and full-size SUVs.

Designed for maximum safety and prestige, the HO9 horns ensure your presence is felt with a serious, robust sound that demands respect on the road.

Key Features:

• Ultra-Low Bass Tone: The 330Hz and 400Hz frequency pairing creates a rich, deep acoustic profile with enough "weight" to cut through heavy ambient noise.

• 112dB Output: Exceptionally loud and crystal clear, providing a massive volume upgrade over weak, thin-sounding factory horns.

• European Luxury Style: Engineered to replicate the harmonic, sophisticated sound signature of premium international automotive brands.

• Slim Design: Despite their deep acoustic resonance, these horns maintain a slim profile for easy installation behind the grille, even in modern vehicles with limited clearance.

• Proven Durability: Built to withstand moisture, dust, and extreme temperature fluctuations for consistent performance year after year.

• Plug-and-Play Ready: In most applications, these horns can be connected directly to your vehicle's existing wiring for an immediate and effortless upgrade.
