    Video Review & Installation

    This Hella Twin Supertone Horn Kit is for those of you that have a 1987 and up Wrangler and are looking to change up the way that your Jeep sounds but we're not talking about exhaust. Right out of the factory your Jeep has a horn that sounds maybe a little bit weak sometimes and especially if you have a big, lifted Jeep that looks really mean, you want it to sound mean when you hit the horn and that factory horn just isn't gonna do it. So, this setup here is going to be a bi-tone horn, it's gonna give you a really rounded sound, it's going to be a very loud sound, and it's going to match the personality that your Jeep has a lot better than that factory horn does. This is going to be a kit that's gonna be pretty easy to install, although it is going to require a little bit of wiring. These horns are going to draw a little bit more power than that factory horn does, so you are going to wanna wire in the relay that comes with this kit, so I'm gonna give it a two outta three wrenches. But overall if you are looking to change up the voice of your Jeep, this is going to be a great way to do that. As far as the construction goes, these are a very well-built horn. These are going to be metal construction, they have these red metal grates overtop of them to keep them protected, they have a mounting bracket that comes attached right on them. Right here you have your two tabs, that's where you're going to attach your wires. And you do have two horns, this is the twin supertone kit, because this has a 300 hertz and a 500 hertz horn, so that's how you're going to get that very well-rounded sound. One's a little higher, one's a little bit lower and they just work really, really well together. Now over here what you have is the relay. And like I said before, these draw a little bit more power than that factory horn. So in order to get the most out of the horn, and also to make sure that you're not going to blow any sort of fuse, you are going to wanna power these through that relay, so you're gonna have to get the relay power directly from your battery. You are gonna wanna fuse that, then you're going to pick up your trigger from your factory horn and then have the relay power the horns from the battery, that's going to give you the full amount of power that you need to get these things as loud as they can be and also like I said before, not to blow any fuses or cause any other electrical issues on your Jeep. So like I said before, I'm gonna give this install a two outta three wrenches, probably around an hour's time to get this installed, maybe a little bit more. There is going to be a good bit of wiring involved in getting this set up, so if you're uncomfortable with that, if you don't wanna tackle it, it's okay to take your Jeep to a shop and have these installed by someone else. But if you are somebody who's into automotive wiring, if you wanna figure this out and you wanna learn, this is going to be a good place to start. Now like I said before, getting the horns installed themselves is very easy, they come with a mounting bracket, you can use any number of holes, drill a new hole. Doesn't come with any hardware but go ahead and get these attached, probably right up in the front of the Jeep right behind the grille is where you're gonna wanna get these mounted. Once you have them mounted then you're gonna start with the wiring. So you're gonna use that factory trigger, that factory horn switch, to trigger your relay to power these horns. So you're going to tap into that factory circuit, get that hooked up to your relay, then you're gonna fuse power directly from your battery into your relay as well, go from the relay over to the horns and make sure everything is grounded properly. These horns come in at $65 and I think that's gonna be a really good deal for what you're getting. This is going to be a very loud setup, they're very well built, they're gonna last for a very long time. You're getting two horns so you have that bi-tone really well-rounded sound. I think if you're looking to change up your horn, going with something like this is going to give you something very high-quality, very well built, gonna last a long time and also give you the sound you're after for a very fair price. So if you're looking for a louder horn to match the look of your Jeep, I definitely recommend taking a look at this kit from Hella, and you can find it right here at
