HELLA H31000001 Sharptone 12V High Tone/Low Tone Twin Horn Kit with Yellow Protective Grill, Includes Relay, 2 Horns

Poor sound quality i give this product in one month before in many time in repair very poor bad product

These horns make a great sound and are louder than stock horns. Each horn is not much larger than the single horn that was in my 2008 Mazda Miata so there was no space issue to mount them. They come with a relay to provide more power, but my car was fused to support both horns. Each horn is a different tone so the two make a great two-tone sound together. The wiring attaches to spade lugs on the horn which were the same size as the spade lugs that the original horn had so I didn't need to change the connectors or wiring to install them. I just had to add a second pair of wires to connect the second horn. I wanted a louder than stock horn because the Miata is a small car and inattentive drivers sometimes turn into my lane because they don't see the car. One beep from these horns quickly gets their attention!

Great horns but the packaging needs to actually protect them.

Pas super évident à installer quand comme moi on n'y connait que très très peu en électricité. Montés sur une 350z, j'ai l'impression que le niveau sonore est seulement un peu plus élevé que les trompettes d'origine (malgré l'installation du relais). Elles respirent cependant la qualité et sont assez esthétiques !

Muy buen tono, pero algo complicado en instalar, no tiene un manual, cómpralo solo si eres ya diestro en instalar estos, o llevarlo a un técnico para su instalación

I cheaped out and bought some hella trumpet horns previously. They were a disappointment. Better sound, but not enough volume. Fast forward to these Hella Sharptones. These are made in Hella's India plant. Not quite as nice as the US or German variety, but they work just as well. Comes with the 2 horns and a 30A generic relay (Not a hella relay like the trumpet horns!). The relay isn't needed unless you plan on wiring a switch on your car. These little horns take around 4A each (8A for 2), so any car can have them wired directly without an additional relay. My little Nissan leaf only has a 15A relay with a 10A fuse and these things work fine. They are SUPER LOUD. At 4 ft, I measured around 105-110db. Pretty close to their 115db rating. They are directional though, so when you blast your horn, people in front will hear it a lot louder than elsewhere (but that's where you need it!). My only one peeve, is the horns "warble" a tiny bit. I'm not sure if it's the mounting, or just sound disortion. Not a huge deal. Overall, BUY THESE. They work extremely well! And unlike trumpet horns which you want to aim down (to prevent water pooling), these aim forward, where you need the sound to go.
