Wolo (417) Long Horns Big Rig Sound - 12 Volt, Low and High Tone

These horns are pretty loud and they help give my little 1996 Geo Prizm a bit more bark when it comes to alerting other drivers or scolding hooligans on the road. I wouldn't say they're even close to as ferocious as an actual big rig's horn, but for the price, I can't complain.The installation was pretty easy, though the trumpets are a bit long, so you may have some trouble finding a suitable location to position them. Luckily I was able to tetris them into my compact car's front end.I've had them in for a bit over a month now and they still work fine through my light usage. I'll update this if they fail later on for whatever reason. Keep in mind that the compressor uses more power than many stock horns (especially in small cars) and you'll want to swap its corresponding fuse with a 30amp one

*Wolo Model 417 Long Horn Plastic Dual Trumpet Big Rig Sound Air Horn Kit - 12 Volt *FIRST OFF...THIS IS LOUD...Every time I honk it everyone around my car jumps. It also has a very distinctive sound. Funny enough, my daughter couldn't find me after her school dance, so on a whim I thought I'd honk my horn and, you guessed it, she found me in 10 seconds. When she got in the car she laughed and commented on how she new that had to be me because no one has a horn that sounds that cool. Now I'd like to add, it's not as loud as the awesome big rig horns, but it's way louder than I expected.SECOND TO NOTE...IT WASN'T HARD TO INSTALL...It literally took me about 30 minutes. I opened the wheel well to the horn, disconnected the wire connectors, studied the opening and mounted the system, faced the horns down(mainly to avoid water damage, but also set to face towards an opening so the sound isn't muffled much). It was seriously a piece of cake.LASTLY...There is a very slight delay, but it's so minor I'm not sure that I would have noticed it if another reviewer hadn't mentioned it. If you end up buying this horn, sorry if that last bit of info bugs you, too.You should check out my pic of my hotrod...I figured for the fantastic price I'd try it and if I didn't like it I'd put my Ooga horn back on. WELL...NO MORE OOGA HORN, okay, I may put it back on, but with a flip-switch. This horn is definitely staying on. I can't believe what a great deal I got on it.TWO-THUMBS UP...TWO LOUD THUMBS UP, THAT IS!

After several days of driving along careless a*holes driving SUVs (which and neither "Sport" nor have any "Utility" in them, except to bully their way through traffic), I've decided to buy the Wolo 417 Long Dual Air Horns. It was a huge challenge to install them inside the front fender of my 02 Volkswagen Golf GTI alongside the OEM dual electric horns, but I managed to bolt and rewire everything really tight and neat.They DO sound louder than any factory horn and their desperate note scares the crap out of any reckless SUV driver trying to cut me off.The air compressor seems a little weak for the size of the horns, and after reading some comments I agree: These babies deserve a much powerful air compressor (the Wolo 808 heavy duty compressor)For the price and the sound you get, buy them. If you're not skilled or have the patience for work for two hours under the fender to figure out how you will fit these LONG horns, don't. In a pickup truck or big Detroit cruisemobile they most certainly can provide a more relaxed fit.For a plus, I think next month I will buy Wolo's more powerful replacemente compressor (model 808) and for the real kicker I'm thinking in how to ADD (instead of just replace) the second compressor alongside the original, so I can get some 35 psi of air pressure, instead of just 12 psi. Most buyers of these horns are already doing this, so if you have the cash, buy 'em both at the same time and please comment on the outcome.

AWESEOME.OK, build quality feels just adequate, especially the plastics. And you are very much on your own for installation including wiring. Nothing in the kit broke as other users have complained. I am in rather mild climate (N Texas); perhaps other users are in very cold climates? I had a smaller Wolo on a truck for 10yrs with no operation or material issues.This is a great horn kit. Large heavy compressor, a bit bigger than a Coke can, and 2 rather large trumpets.I had good luck mounting behind the headlights of my 1ton Chevy. Lots of room in there, horns are pointed down and unobstructed. It's not a 'train' horn, and not a 'deep' bellow. It is a medium-toned, hairy-chested BLAST. VERY high volume, and no noticeable delay as the compressor cycles on. Fantastic. Recommended.

I put these in my truck in the middle of january,they sounded good , junk on february 20th. Compressor was spinning but trumpets wont sound.Big disappointment. P.S. No warranty. Okay bought another set from a local retailer,paid double the price but needed a working horn to pass state inspection. They do sound good, let's see how long they last?

It just OK, off key, and not really loud in traffic.Easy to install if you have the room to place 13" long trumpets. Everything is plastic and pot metal. They sound OK for the construction, but the tuning is off-pitch so that nice horn harmony is missing. The frequency is mid-range low, and travels well, but the lack of loudness against basic traffic prevents it from being a true attention getter. It might be crisper and louder with a single compressor feeding each horn. Replacing them with the much louder, smaller, high pitch Wolo Air Max.
