Best Horn EVER!
By Andy
OK I have a big truck, and don't want a wimpy horn...Who doesn't? About three years ago I bought a cheap set of WOLOs with a two plastic air horn set up and a small on demand compressor, and they sounded ok...for a while. Living in Alaska, where we are subjected to lots of crazy weather, the ole plastic horns deterioated and sounded worse than stock. Thats when I decided to "Go BIG or Go Home!" I purchased the cannonball express and the only complaint i have is they are so big i t took forever to find a place for them. I finally mounted them inside my bumper where it has a mount for a winch. These horns are HUGE! you need a spot approximaly 1ft wide x 1ft high x 1.5ft long to get them mounted in. Is it worth it? OH YEAH! These things will make an unsuspecting person wet themselves!!! AWESOME!

By scott
This thing is great. Ive had it on my truck for three yrs. and its a BLAST. Literally. I got the air tank and the air pump for it. I mounted it in the best place I could think of. I took the spare tire off and mounted it under the truck. facing forward and have not had any problems with it. I have a lifted truck so the spare wouldnt of done me any good anyway, because I also have oversized off road tires. nobody even knows I have it. So if you dont want anyone to know you have this giant horn. I would recommend you mount it under the truck where your spare time is. It makes everyone jump. I love it.

Nice Construction, but not as loud as others.
By Thomas E Ridgaway
I have owned these horns for a couple months now and would NOT recommend these horns.I have been buying and using air train horns on my trucks for over 20 years. Wolo has some fairly good products overall for being Chinese built. I bought this horn to replace another dual air horn and I thought it would be loud. It isn't.I have a very nice Airraid 200PSI 12v compressor and big tank to push my horns and suspension air bags. I have a 150psi regulator for the horns. My 11 year old shorter, smaller duals are louder than this triple unit. It came with a 1/4" air valve, which broke and leaked within one week. I contacted Wolo and they sent a new one right away. At first, I thought the low output volume was due to the bad valve, but the new one did not increase the airflow nor the loudness of the horns. I think the valves and manifolds into the horns need to be 1/2" to increase the air volume into the horns to increase the loudness. I can't fix that. Since I have had these on my truck a while, I can't return them so I am going to have to sell them on eBay or Craigslist- dangit.Do your homework and go with a something different.
