Kleinn Air Horns Trail Blaster Air Horn Kit for 07-18 Jeep Wrangler JK

I found my compressor to continue to recyle ever few minutes. After checking for leaks, I found the issue to be in the plastic tubing. I replaced the tubing with copper coil tubing, and the problem of recycly continuously went away! Yes, the compressor is pretty load, but no more than it now comes "on", its acceptable.

The horn sound is good and it is very loud.
Installation is a challenge - I agree with the comments about the bracket holes not quite lining up - I had to expand the bracket holes using my drill.
The biggest issue, as others pointed out, is that the rear differential hits (and bends) the bottom of the tray / bracket. This pushes the tank and compressor into the floor of the jeep making it even louder when it turns on. Small frustrations mostly, but all could have been solved with better engineering at Klein.
Quadratec was good about sending a replacement when my first compressor didn't work. I like having air horns but for the money I expected better quality.

Had it installed yesterday. Horn is really loud, just what I was looking for....But, as a couple people have mentioned, the compressor is Very loud and actually vibrates my JK. It takes a minute or two, and seems to happen every time you start ignition. One would hope you could do a quick errand for 10 minutes and not have it run again when you return to start Jeep. I am going to install a cut off switch so I can fire it up once in motion, rather than have people looking at me in the parking lot wondering what is wrong with my Jeep. Its also going to be something you have to explain to any passenger that doesn't know up front when your little compression friend kicks on underneath you. I understand from other reviews that this can happen randomly during any trip when tank needs pressure. Have not experienced it yet, but I'm sure it will more than wake me up if it kicks on on the highway. I will report back after installing kill switch, which will act as off/on switch. Problem is, I'm sure there will be times when I want to blast someone when I haven't "charged" the tank.
