The horns arrived in a Hella cardboard box, nothing special here. The only thing it comes with is a relay and the two horns, nothing else. No wires, connectors, nothing. I expected this so in case it wasn't clear, now you know. Also, the horns are most definitely RED. Don't be fooled by the picture here. They are NOT black. They are RED. Not that it mattered to me since they're hidden behind my bumper.
Installation instructions are virtually non-existent so if you're the type of person that can't figure things out for him/herself, you may want to get some help, or have someone else put it in for you. The only thing included is a little relay wiring diagram which shows you which connector on the relay goes to what.
In my own case, I did NOT need to use a relay since my car (and most modern cars, if I'm not mistaken) already have a relay for the stock horn. I was able to reuse the connection on my stock horn for the (+) connection, and I wired up a (-) ground directly to the chassis. Note: EACH one of these horns uses 6A of current, for a combined total of 12A. So make sure you select an appropriate gauge for your wires.
These horns were a tiny bit larger than my stock ones, so I had to loosen up the tightening nuts on the rear so that I could pivot the bracket a bit.
After installing, I tested them. They sound a bit louder than my stock ones even though my stock horn said 113dB on them and these are only 110dB. Go figure. The tone is definitely deeper/richer than stock... it has that European sort of sound.
All in all, a good buy, and I recommend it, but make sure you are comfortable with wiring things up!
I recorded a video clip of how the horns sound. Go to https://www.youtube.com/watch?v=WzLIdYVzc2o.
I removed the oem horn and put a relay on those wires. Now I switch the oem horn and these two on that relay and have a much more robust big truck sound. I put these facing downward and fwd on my front bumper so they're exposed to the elements and no sign of rust etc, they work well.
Admittedly I'm an a-hole and I have no patience for people on their cell phones that aren't paying attention, people that dilly-dally around, people that just can't decide whether to go or not, old timers, anyone in a Prius, people that have no where to be on any given day or that have no business possessing a drivers license etc . . . all the Mr. Magoo stereotypes. All the other stereotypes.
This combination gets attention and means business. I might even buy another set :D
These horns have separate connectors for positive and ground (whereas most stock horns use the bracket as the connection to ground). I had to make a small pigtail with a female quick-disconnect connector and a ring terminal that I connected to the mounting bolt. The positive terminal easily connected with the stock wiring, and will do so on most cars.
The twin-tones make for a classic horn sound like the ones on larger cars from the 70s as opposed to the tinny sound of compacts from the 80s and 90s. They're loud enough, a little louder than the stock horn. I understand that Hella makes Supertone horns too, which are supposed to be louder, but sell for over twice the price. My advice is that if you want this type of horn sound but louder, just buy 2 sets of these. They'll be louder and cheaper than the supertones.
The horns have a solid feel to them, and the plastic trumpets will resist corrosion. The brackets look zinc-coated as well. It would have been nice to be given an option pigtail to ground the bracket, but I easily made one for a few cents. Overall, for the price, these horns can't be beat.
