ZONETECH 12V Single Trumpet Air Horn - Premium Quality Silver Alarm Relay Included Chrome and Compressor Super Loud 150db for Truck, Train Lorry, Boat and SUV (1-Pack)

This thing isn't going to win any awards for fit and finish but at this price point I'd consider it a good value. Materials aren't much more than adequate but nothing felt flimsy and the whole thing went together and works as advertised. They even included some small rubber pads for the horn mounts to reduce vibration so that was a nice touch. The air hose doesn't seem like great quality but the stuff is cheap at Lowe's and easy to replace whenever it starts cracking and leaking. I had a tough time finding a place in my engine compartment where this would fit but I knew what I was getting myself into.The sound quality is clear and robust with a mid tone that doesn't sound high and piercing but also isn't too low and sound like it's pretending to be something it's not. Sound volume is robust and far above average for stock or probably even aftermarket horns. It's loud enough that I'm concerned they'll say it's too loud when I take it in for inspection but we'll see. Texas law only says it shall not be "excessively loud" whatever that means.My last horn that gave out was a similar can-compressor style horn like this but with a smaller bell (Wolo big bad something or other, do not recommend). I think it gave out because it was mounted low and got exposed to a lot of water, so this time I mounted the compressor higher in the engine bay where it's more protected. In a few months I'll update with how it fairs after some heavy rains and puddles. Happy so far for the price as long as it keeps on working!As a bonus, the poorly translated instructions are a pretty good laugh.

This horn was reviewed online and it matched up exactly as advertised. Very loud. The only problem was the included relay did not work out of the box. Popped the relay open and found TWO broken solder joints inside. Resoldered the joints and it works well. For the price they charge perhaps the cheaped out on the relay. Good product for the money however.

I bought one of these some time back and just got around to installing it yesterday.The install was easy. First off, toss the instructions in the trash unless you can read gibberish. Second, I have (had) 2 factory horns in my 98 Dodge Dakota. I simply unplugged 1 and cut the plug at a length that I could later put it back on the truck if I want to. I soldered speaker wire to the existing horn wires, ran those to the compressor, and soldered those onto the compressor. Finding a place to mount the compressor was the hardest part, but still easy enough.I also made the hose as short as possible (about 6"). Make sure your positive and negative are correct before doing any soldering. The horn will not sound loud if they are incorrect.The relay that came with it went in the trash along with the gibberish instructions. It's really a simple install.The wife and I took a ride around to test it on the public. Lots of fun! We got a lot of laughs from most folks, though some were more inclined to give us the middle finger. ;)I figured I would write a review since I am on Amazon today to buy another one to replace my other factory horn!

Garbage! Thing came damaged almost looked like it was a return and then resent out. Compressor was broken and horn was dented. No wires, fuse box or switch included. Instructions were extremely vague I do not recommend this item.

What a deal You get the Horn a Compressor a Relay and Air line and some mounting hardware. The only thing I needed to add was a fuse holder and fuse and some 12 gauge wire and crimp on lugs. I installed this on my Pontoon in about 20 minutes. LOUD HORN gets attention when you sound it like you should.

It was nice and sounded just how I wanted but throughout daily driving the compressor got dirt or moisture in it and still worked but only blew about 1/3 as much air so I took it off

Bench tested this horn in my garage before attaching to truck, left my ears ringing. At 12.8 volts, the compressor pulls 21.5 amps so make sure you buy a proper relay + harness to wire this up. I picked a well-rated harness and relay kit for 8 bucks and it made the electrical installation a breeze. I have a Nissan R51 which doesn't really have lots of room in the engine bay for this thing and I did not want to put it across my grille. Some people put them in their bumper but that really kills your volume output. I ended up installing it between my frame and my wheel well with the horn facing the ground. With no obstructions between the horn and the outside of the vehicle, this thing is obnoxiously loud. I purchased this after being hit on the highway and I feel confident that this horn will be heard much more than my stuck horn at highway speeds. Hopefully I don't have to ever use it but like having the reassurance that its there.
