Frequently Asked Questions
What is a custom car horn?
A custom car horn is any upgrade that replaces the weak, single-note factory horn with something louder or more distinctive. It covers three families we carry: simple 12V electric horns that bolt in where the stock horn was, musical horns that play a tune, and full air horn kits with a compressor and tank for the loudest setups. The right one depends on how loud you want to be and how much room you have to mount it.
How do I replace the factory horn on my car?
The simplest swap is an electric horn, which uses the same 12V power the factory horn already runs on: unplug the old horn, mount the new one securely, and reconnect power through a relay with a clean ground. A weak ground is the most common reason a new horn sounds quiet. If you want far more volume than an electric horn can give, an air or train horn kit is the next step up, though it adds a compressor and tank to mount.
Which custom car horn is the loudest?
An air horn kit is the loudest option that still fits most cars, because it drives real trumpets from a compressor and tank rather than a small electric diaphragm. Space for that air system is the limit on a car, so kits whose trumpets mount individually, like the Rocker and Conductor's Special, are the easiest to fit since the horns can be spread out. The 2-Chime and 4-Chime kits are more compact overall but each horn is a single unit, so they usually need grille or front-bumper space. Electric horns are far easier to install but stay well below an air setup on volume.
What custom horn sounds can I choose from?
Several distinct types. Musical horns play a tune, like the Dixie and the La Cucaracha. Air and train horns give the deep locomotive chord. Public address units add sirens and a microphone on top of the horn output. And plain electric horns give a stronger version of a normal horn note. Pick the sound first, then match it to the space and install effort you want to take on.
Are aftermarket car horns worth upgrading to?
For most drivers, yes, because the factory horn is built to a price and sounds it. An aftermarket horn is louder and more distinctive, and even the simplest electric horn swap is an inexpensive and clear step up. If you want to be heard from much further away, an air or musical horn changes the sound entirely rather than just making the stock note a little stronger. The upgrade is as big or as small as you want.
