The Sonic Horn vs Boom Blasters
Which custom car horn actually wins? Your Car…… Your Sound.
Looking for the loudest, funniest, most head-turning custom car horn out there? You're not alone. The roads are full of cookie-cutter cars, and if you're anything like us, you're sick of sounding like everybody else. Two names come up again and again in the novelty car horn world: The Sonic Horn and Boom Blasters. So which one actually wins? Let's break it down, honestly.
What Is a Custom Car Horn?
In short, it's your car's personality in audio form. A custom car horn swaps your factory beep for whatever you want — a musical horn, an animal sound, a movie quote, or a flat-out "get out of my way." You load your own sounds, hit a button, and turn heads. New to the idea? Here's how The Sonic Horn works, and a library of free sounds to play with.
The Sonic Horn: The Modern Customisable Horn
The Sonic Horn is the new kid on the block, but don't let that fool you. It's built around doing one thing brilliantly: letting you put any sound you want on your car.
- 130 decibels of pure attitude — well past your factory horn's ~110 dB.
- Four custom sounds — drag your own MP3 or WAV files on over USB and swap them whenever you like.
- Works on Mac and Windows — it shows up like a USB drive, no clunky software.
- Wireless 4-button remote — fire off any of your four sounds on the move.
- Water-resistant — mount it in the engine bay and don't sweat the rain.
- 30W class-D amp, runs on any 12V vehicle — cars, trucks, Jeeps, boats, golf carts.
It's less a toy and more a customisable sound system for your car. Want the full picture? Read the install guide or browse the free Sound Clips library.
Boom Blasters: The Established Name
Boom Blasters has been in the novelty horn game since the mid-2000s, with a big catalogue and a loyal following. Their programmable horns, like the Big Bubba, hold a handful of sounds, come with a wireless remote, and wire into a 12V system. If you want an established, budget-friendly option with lots of models to choose from, they're a genuine choice and have earned their reputation.
Where they tend to trail the Sonic Horn is on the modern touches — things like easy Mac support and a higher volume ceiling, where some of their models sit lower. Specs vary across their range, so it's worth checking the exact model you're looking at.
Worth knowing if you're in Australia: Boom Blasters ships from their US warehouse, so factor in international shipping time and customs. The Sonic Horn is set up for the Australian and international market from the ground up.

The Verdict
If you want maximum loudness, easy customising on any computer, and a genuinely modern bit of kit, The Sonic Horn takes it. It's the loudest, most flexible novelty car horn we'd happily bolt to our own cars. Boom Blasters is still a solid, budget-friendly pick if you want something simple and proven with plenty of models to browse. But if you're building a ride you're actually proud of, especially if you're shopping for a programmable car horn in Australia, why settle for quieter, less flexible, and a longer wait at the border?
