Piaa 85110 115db 400HZ + 500HZ Sports Horn

I assume from the other reviews of this product here and around the net that these will fit and work on most cars, but my review will focus on my experience installing them on my '97 Jeep Wrangler. My twelve year old Jeep Wrangler horns sounded pathetic. I don't know if they sound like that when new (I bought my '97 in 2005), but even at seven years of age, those horns sounded weak and were pretty embarrassing to use. I considered going with the higher frequency version of these horns, but after listening to both frequencies on Youtube videos (just seach "PIAA 115db"), I decided that a real American Jeep (well, made in Canada) needed a "REAL-American" sounding horn, so I stuck with this classic sounding horn, rather than going with the sound of the higher frequency version option (which would be a good choice for import vehicles). I'd say that this horn has pushed my horn volume to at least stock, if not 10-20% louder than stock, of a fresh Jeep Wrangler horn (which my neighbor has on her 2009 Wrangler). Install/Technical Notes: Assuming you have some basic hand tool skills, have a a couple of pair of vice grips, a wire striper/crimper, a volt-meter, a few .5"-1" long, 1/4"ish wide bolts with nuts & washers and perhaps a 14-16ga female wire connector splay ends, you should be able to swap these out with your current Jeep horns in about and hour. I'm sorry, but It's been a while so I don't recall exactly what came with the horn kit, but I think it included a few auto-crimps that might work as well, if your not willing to do the job "right", speaking as an off-roading jeep "fan-boy" who has built-up his jeep correctly with his own two hands. I noticed that the horn body widths, as well as the horn mouths, were moderately larger than the stock horns on the Jeep, but they were the same basic design (that's good news). The horn mouths also had plastic sheilds covering the opening which the stock horns didn't have, but that seems like a good idea to keep the new horn internals from getting splashed with water over the next decade of use. Though I was concerned about how I was going to mount these to start with, I found that I could use the existing horn mounting brackets of my Jeep if I just bent the horn brackets (those that are on these new horns) 180 degrees back onto themselves at the middle of horn using two pairs of vice grips (The original Jeep horns do not have that bracket you see sticking out on the stock photo of the horn, but instead simply mount directly to the Jeep's horn mounting brackets at the center of the stock horn body via a post and nut solution, which is not doable with these new horns due to a shorter and wider post (ah heck, see the photos I posted if you can't figure out what the heck I'm talking about!) After insuring I was getting the power and ground wires connected to right posts on the horns, they worked just fine on the first try. You don't really need to remove horn mounting brackets from the Jeep like I ended up doing; you'll just need to adjust the angle of the new horns a bit to insure that they don't make contact with any of the surround jeep parts before you tighten them down. As I recall, the instructions which came with these horns were very clear and provided different wiring diagrams for different potential wiring solutions. This made it very easy to figure out that I did not need to add a new ground wire for the Jeep... just use the two wires per each horn as the stock jeep horns use. While these horns do not provide an air-horn level of volume, they do provide the same general design and mounting as the stock Jeep horns, with the same or better durability and volume than stock, without the hassle and time required to install less durable air-horns and compressors. That makes this a true winner solution for REAL Jeeps used for their designed purpose of off-pavement travel. Highly Recommended for Jeep Wranglers!

Surprisingly loud! Holding each in my hand & applying 13 volts one at a time they are a bit louder than the FARBIN I also have. They pull about 2-2.5 amps and the farbin mentioned pull about 4 amps. I'm using relay to be safe and running all 4 at once! But It's obvious though you should not need a relay if running only the piaa pair. I have the 400 - 500hz which is perfect & plenty alarming! If you choose 500 - 600hz ppl say it sounds like a European sports car "not what I want" The problem with going too far off the map in sound frequency (ie: using a train airhorn etc) is that the other driver will be confused as to which vehicle it's coming from. So imo good to stay fairly close in pitch but just go louder. The stock horns on a RAV4 are a joke maybe 50 percent bigger than a silver dollar! This is an easy solution without messing with relays.....(only 5 amps together) you may could run both these and stock in parallel but you'll be close to your max amps of 10 without a relay. Some have used a 15 amp fuse running 4 together and only using in short burst may be ok otherwise your chancing melting your wiring harness unless you keep your 10 amp fuse. Those wires are pretty tiny that run to the horn on a RAV4 !

To start, my '06 Vue came with a single round type horn that sounded no better than a bicycle horn...pathetic to say the least and it wasn't getting anyone's attention when needed. So I looked online for replacement horns and compared this to the Hella Horn Supertones (Round Type) & Premium Bass Horns (Trumpet). Ahead of time, I knew I had enough room behind my bumper where the existing horn sat to use a trumpet style horn, so I considered that type as well. Firstly, both PIAA and Hella sell twin horn kits and since I only have a single horn, I knew mechanical modification would be required (i.e. making a bracket to hold the second horn) regardless of which brand I bought. Secondly, the Hella horns came with an added relay, which I didn't think I needed, but I truly wanted something that was "Plug & Play" electrically...or at least with as little modification as possible and the PIAA states that an added relay wasn't required. I'd read also that the Hella horns didn't come with installation instructions. I found that a little hard to believe in this day and age, but nevertheless, using the interwebs I was able to find some installation instructions illustrating the wiring required. Lastly, I also listened to the sound comparisons on YouTube and that solidified my decision as I had liked the sound of the PIAA horns over the Hella Supertones and Premium Bass horns. PIAA also sold the 500HZ + 600HZ Sports Horn, but I felt that it would be too loud for the area that I live in as our houses are relatively close to one another and the horn does sound when the alarm & remote start is activated / utilized. Installation was rather simple. The installation manual illustrated four possible existing scenarios that your car's horn setup might have been, the tools and additional wiring (if any) is required, and the illustrations were rather easy to follow...especially if you are able to identify the existing positive and ground wires on your car. Once installed, the sound was better than what I had expected (sounded similar to a NYC Taxi Horn) and paid off immediately as I pulled out of my driveway and honked at the kids playing a little too close to my driveway.

J'ai reçu avec étonnement le klaxon dans un emballage destiné au marché local japonais et non celui destiné au marché international. Bon à savoir: L'emballage japonais affiche 112 db et l'international 115db, soit deux fois moins fort. Il s'avère qu'après traduction en ligne de la notice, c'est bel et bien le même modèle (85110 ou H0-2). Alors d'où vient la différence? Tout simplement de normes de mesure diffèrentes: 2m à l'international. Pour le japon: 7m depuis le 01/01/2016. Avant cette date, 2m comme partout ailleurs. La preuve en photo (l'encart central).

Excellent value.

Installed on my 2010 Honda Fit. Direct swap without relay ( these horns draw 5.4A only). Only thing I need to make is a connector to the stock honda connector. Whole assembly took me under 15 min. Great rich European car sound and much louder than stock meep meep. Great product.

Las cornetas que vienen de fábrica con mi vehículo Volkswagen (marca Claxon, hechas en Francia) tienen 20 años de edad. Nuevas, cuestan menos de la mitad que estas y sin embargo, suenan con mucha más potencia que estas. Definitivamente, por ese precio de venta, yo esperaba mucho más. No las recomiendo en absoluto.

The sound isn’t loud as per description.
