Easy to install except when you have to hook up the blue wire to a button.

It is pretty loud. I mounted mine up front, directed at the ground. I also cut a clearance hole out of the front Valance (old car) so it is wide open for sound and it bounces right off the roadway in the front.One surprise is the instantaneous full volume. I have used Air horns on big rig and installed sets on pick up trucks; that have a 'build up time.' That allowed me to tap the existing horn with less volume, without getting the full blast of the Air Horns. These are FULL volume immediately and startling, so be careful in the use. I did not like the motor housing as it did not look like it was sealed against weather. Mounting instructions are more so 'under hood' so I sealed the bottom of the housing as well as the elec connectors with RTV. It did not effect the horn's air intake - don't forget it has to draw in air for the compressor. We'll see how long it lasts.

It works as it should for the price. Not super loud but louder then the stock horn on my daughters Honda civic. Easy to install

Not too loud, works fine
