i looked at various hella twin horn setups (owned the set found in griot's catalog many years ago) before finding these. i made a quick visit to youtube to see if i could find sample sound bites of the hellas vs. these, which i did, and after listening to them decided to go with the piaa's.

like another reviewer, i chose the higher tone (500hz and 600hz) piaa's because to me they sound better, or more unique, than the lower tone ones, which sound like a stock american horn.

i installed these on a jeep wrangler, whose stock single factory horn is anemic and dangerous, since it can barely be heard. the piaa's come with very clear instructions for installation. you simply match up one of 4 diagrams with your factory setup and then follow the simple steps in the instructions to wire them up.

you do not need a relay to install these. i did have to tap into my existing positive and negative factory horn wires, since i was going from one stock horn to dual horns. piaa provided the extra wiring to do this and the quality of the wiring and spade ends is excellent. i did have to go buy two female spade bits for the ends of the factory wires, since i had to cut those off the factory harness. crimping on new spade ends was not hard at all. the whole install took about 15 minutes and the dual horns fit perfectly in the stock location.

i am very, very satisfied with the piaa sports horns, in terms of both loudness and quality of the sound. i was a little skeptical because of their low price, but they really do deliver, and i think they are better than the more expensive hellas. they seem well-made and combined with the great instructions, i don't see how you can go wrong. highly recommend.

Just traded my Nissan Armada for a Toyota Prius. I love the Prius, but the horns it came with were very disappointing. After doing a little online research I found these horns. This kit actually contains two horns: one 500Hz and the other 600Hz.

There are two versions of these horns: a lower pitched one that sounds like a typical American car horn (400Hz horn + 500Hz horn), and these horns which are slightly higher pitched and sound like a European sports car (500Hz horn + 600Hz horn). I found sound recordings of both horns online and decided that the sound of these horns would more fit the Prius. If you want a more traditional sound, go with the lower pitched horns.

Installation was very easy. I was able to install in the stock horn locations; no relays required. I ran the grounds to the mounting bolts. I now have no problem being heard on the freeway.

I bought these to replace a "Bad Boy Air Horn" which had failed after only 2 years. The first thing I noticed was that they were really well made, and had a quality feel about them. The second is that they were fitted with a splash guard over the "mouth", which I haven't seen on any other horns.

Although these were very easy to fit, I was disappointed that the kit came with no mounting hardware, relay, or wiring, not a big deal, but at the price would it have killed them to have included a couple of nuts and bolts?

Now the bottom line, how do they sound? Answer, great! They are as loud as the old "Bad Boy Air Horn" but they have a much better twin tone sound. Also, unlike the air horns you can actually "beep" these, which is great for getting someone's attention in traffic without resorting to a full on blast.

Finally, as these were being fitted to a Toyota Corolla I opted for the 500hz/600hz high tone, and it suits the car perfectly. They also make a 400hz/500hz which sounds like a typical American car, and a 330hz/400hz which would sound great on a truck.

I would say the 400-500hz horn sounds far better than this one. this one has a flat sound and doesn't have that scary effect like the other. unfortunately i bought the 600hz one looking at the good reviews here. I didn't know about the difference until my wife said it sounded flat (Though louder than OEM, i didn't like it)and until i watched the utube comparison video! I guess the bad reviews for the 500hz by some is just fake and probably people behind other brands. PIAA is made in Japan not China.

These have been GREAT! Everyone loves them, except the Prius in front of me.
I just spliced them in to the factory wiring, leaving my factory horn plus these installed. I was a dealer tech for 12 years, specialized in electrical and fuel systems, and ASE certified in Electrical. I see no reason to go through the trouble of relays etc. If you are just hitting these for short bursts, the amperage draw required, will not be enough to heat the wires, or draw enough to blow fuses.
At least not on my 2007 Acura TL..
Super happy with these…

I purchased these horns to replace the horn on my BMW bike. The space where the original horn was located is somewhat small. The horns have a plastic cover over their opening. I had to remove these covers to make the fit much easier since they add bulk in a small space. Luckily it is very easy to remove them. I think the cover removal alters the sound of the horns but my main objective was to have extremely loud horns to get the attention of the occasional errant driver. They are very loud and without a doubt you will get the attention of a driver coming blindly into your lane.

I spliced the horns into the existing horn wiring.
