What makes it different

Every other car hornOne fixed sound. Loaded at the factory. Stuck there forever. You get no say in it.
The Sonic HornFour custom sounds. You pick them. You load them. You change them any time you like.

What you get

Any custom car horn sound you want

This isn't a novelty car horn with a handful of preset sounds. Load any MP3 or WAV you have. A movie quote, a sound effect, your dog. Change it again next week. The sound is yours.

130dB through a 30W amp

Your factory horn sits around 110dB. This is a different level. Driven by a 30W class-D amplifier, it's the kind of car horn people notice.

Wireless remote. Four buttons.

Four custom car horn sounds on tap. One press on the wireless remote fires whichever one you want. No cabin wiring. No extra buttons on your steering wheel.

About 20 minutes to install

Mounts in your engine bay with two wires to 12V. No cutting into your existing loom, no tools you don't already own. The install guide walks you through the whole thing.

Fits any 12V vehicle

Cars, utes, trucks, Jeeps, 4WDs, boats, RVs, golf carts, motorbikes, EVs, Teslas. If it runs on 12 volts, this wireless car horn fits.

Your real horn stays

Runs as a second, independent horn alongside your factory horn. Nothing about your original setup changes. Both work exactly as they should.

Before you ask

Does it replace my factory horn?
No. The Sonic Horn runs as a separate, second horn. Your original stays fully working. You get your standard horn plus four custom car horn sounds on the remote.
Will it drain my battery?
No. It only draws power when you trigger a sound. Sitting idle it pulls next to nothing, same as your standard horn.
How hard is the install?
Easy. Two wires to a 12V source in the engine bay. Most people are done in about 20 minutes. There's a full written and video install guide on the site.
What car horn sounds can I load?
Anything you can save as an MP3 or WAV. Grab free custom car horn sounds from the Sound Clips library, pull clips from YouTube, or record your own. You can swap them any time by plugging the horn back into your computer.
Will this wireless car horn fit my vehicle?
If it runs on 12V, yes. Cars, utes, trucks, 4WDs, Jeeps, boats, RVs, golf carts, motorbikes, EVs and Teslas all work.
What's the returns policy?
30 days, no dramas. If it's not right, email info@thesonichorn.com and we'll sort it. Faulty on arrival? Fully covered.
