## Customer Reviews

### ⭐⭐ Not loud
*by K***  on July 10, 2024*

Bought this for my husband after doing lots of research came across this one had good reviews good video. One review suggested a bigger air compressor and gave the exact one to buy so I did and I am not happy at all it sounds deflated, and his stock horn is definitely louder than this. Completely anti-climatic and very disappointed

### ⭐⭐⭐⭐⭐ Good purchase
*by A***N on July 2, 2012*

This horn is a good purchase for between 50-70 dollars. The box arrived quickly and in good shape. It included the correct product, instruction manual and some mounting hardware. Note: if you are intending to mount this horn in any other way than intended be cautioned that it is very large. I didn't want to make it visible and found that it fit well under the rear bumper of my vehicle. Took very little time to install, instructions are straightforward and all the required hardware was included (except drill bits). The horn is very loud and works well. The compressor takes about 1/4th of a second to generate pressure from the time the button is pushed. I recommend buying a better switch to use though, i bought a switch at a local hardware store for less than a dollar which works much better than the included one. Wiring diagram is complete and wiring is very simple.

### ⭐⭐⭐⭐ This is one LOUD horn, but you need a bigger compressor!
*by J***R on April 17, 2015*

This horn is much like what you would encounter on a yacht, or some large trucks. The photo doesn't really give you the idea of its size. It is as long as a regular trumpet, and the bell is just as big around, too. We had a time fitting this in as a hidden horn between the grille and the radiator, but we managed - at about a 45-degree angle. At first, I had it put on with the compressor that comes with it. It made a pretty good noise, but there was an obvious mechanical "buzz" when the compressor started up before it had enough air to make a sound. If you don't mind "Bzzz-HOOOONK," it's OK as is. I upgraded. Wolo makes a higher-output direct-drive compressor, the model 808-C, and I had that put in. I am completely happy with how this horn sounds with that compressor! I have heard train horns like this, but most associate this sound with a yacht. It's fun, and has great "startle" power!
