Loud. That is what these are. I've installed these on my Hyundai Santa Fe as the stock horn on that car is nothing but embarrassing. I managed to replace them with these Hella horns without having to remove the bumper. It can be done by just removing the headlights. It is very tight though! Using some spade connectors, I created a wire to go from the horns to the existing wiring, no need to use the relay that comes with the horns in my case which helped make it even easier. I'm no mechanic by any stretch of the imagination. Really pleased with these although the new sound is different to what you might expect. All I cared for what the loudness and I got it.

Well made (in India), good quality, they produce a decent, loud tone, far superior to the original horn. They come with a Hella relay.

very good set of horns, I'm pleased with the sound and at the price, good value too

Really good loud horns. Box comes with just the horns and a relay though, so you'll have you build your own wiring kit. Avoid buying from "Super Value Shop" if you can - had trouble with my order and their customer service was awful!

Happy with the hoovers, well worth the buy

Thay are NOT loud at all also sounds rubbish .

Very good quality

Not fitted yet. Some installation instructions would have been helpful Box contained just the horns and a relay.

I recently purchased a 2025 Subaru Forester, and it came equipped with a horn that could best be described as well this side of anemic. I can’t quite capture the sound it made, but suffice it to say it wouldn’t have disrupted evening prayers in a cloistered nunnery. Since I live so far out in the rural wilderness that one must walk toward town to go hunting, I regularly encounter a veritable horde of wildlife worthy of the fire scene in Bambi. With that said, I need an authoritative horn—something capable of announcing to the denizens of the woods that a rather large, fast-moving object is arriving and possibly not in full control. After browsing through a digital bazaar of countless horns here in the Amazon mercantile, I decided to take a chance on this pair of Hella horns. I’d like to claim that their extensive technical specifications swayed my decision, but that would be a lie of convenience. The truth is, it was their glorious red, candy-like color that spoke to the tiny child within me—the one who shouted, “I must have them!” With my dubious selection process now exposed, I can report that serendipity decided to smile upon me. These little red pancakes were delightfully easy to install, and—by some miracle—Subaru had already provided adaptable mounting points beneath the bonnet of my worthy steed. When I pressed the horn button, I was rewarded with a loud, two-tone, gloriously raucous blast. The child in me grinned a lascivious grin of delight, and I pressed the button again… and again… chasing endorphins like Pavlov’s most self-satisfied dog. Eventually, I stopped—mostly out of concern for my own moral character. That afternoon, taking the Subaru down the open road, I realized these horns were everything I had been looking for. I should have known—being German, they could produce nothing less than a trumpet of Teutonic glory, as though my Subaru were parked at the gates of Valhalla demanding entrance. To be honest, I now find myself inventing reasons to use them. Each blast conjures the sound of a road rally, and I half-expect a co-driver beside me screaming, “Hard right! Straightaway! Hard right again!” at the top of his lungs. They are, in every sense, a thing of automotive glory.

I’m using Nissan Pathfinder 2018 on OEM wiring and its working better than the OEM horns.

独特ないい音が鳴ります。 PIAAなど他メーカーのホーンとかぶりたくない人におすすめ。

I loved these Hella Supertones. They're made really well, great quality. They're super loud if you install them with the relay, and even without it, are still pretty loud, louder than stock horns. They would scare a lot of people cuz They weren't prepared for how loud They are, and honestly, I wasn't ready for how loud They were, and I jumped the first time I tried my horn after installing them. They look great too, I took the metal grill off of them when I first got them, and painted them white, to match my blue with white rim color scheme on my '04 Subaru WRX, and they just looked so sweet, the white really made them stand out, mounted behind the grill of my Subie. And they're pretty simple and fast to install, only took me about 30 min at most to install them. I got a LOT of compliments on them, and would also get a lot of questions about what they were, most people, that were unfamiliar with them, thought they were speakers. The sound of these are kinda high pitched but deffinitly a huge upgrade of any stock horn, and the look they add, mounted behind your grill, is awesome. Unfortunately my WRX, that I installed these Supertones on, got stolen and never got recovered, so I don't get to enjoy the sound and look they added anymore, but if, or when, I get another Subaru, I will be buying these Hella Supertones again that's for sure. I would definitely recommend these to anyone, especially if you have a WRX or STI they are perfect.
