Chrome Double Air Horn 12V 150 dB

Chrome-plated dual trumpet air horn: the sound you hear before you see the car

This air horn with two chrome-plated trumpets is not designed to be discreet. Two bells of different lengths, a cylindrical compressor between them, a common mounting plate: the very mechanics of road horns, scaled down to fit in a car engine compartment. The result is a deep, full-bodied two-note chord that cuts through traffic noise where the original car horn gets lost. Rated at 150 dB by the manufacturer, it is designed for those who want to be heard immediately.

Two chrome-plated bells that add character to the engine compartment

The polished chrome of the trumpets catches the light as soon as the hood is opened. It is the kind of detail that enthusiasts notice: a visible and proudly displayed car trumpet horn, a far cry from the small black plastic box installed by car manufacturers. The two bells of unequal length are not an aesthetic choice: it is this difference that creates the two-tone chord, the full-bodied sound associated with trucks and tour buses.

On a pickup truck, SUV, or modified sedan, the assembly is prominently mounted on the front crossmember and becomes a full-fledged customization element.

12 V electric compressor, sealed body, and complete hardware set

The electric compressor is housed between the two trumpets and supplies the bells with compressed air with every press. The assembly operates on 12 V and is connected via a relay, never directly to the original switch, which does not have a sufficient rating. The manufacturer claims resistance to water and vibrations: the device is designed to live outdoors, under the hood or in a wheel well. The box contains the mounting bracket, four bolts, four nuts, and four washers, as well as the relay and its wiring harness.

• 12 V trumpet horn — two-note chord produced by two bells of different lengths
• Chrome finish — polished bells that enhance a modified engine compartment
• Integrated compressor — air pressure generated on demand, without a separate tank
• Resistance to water and vibrations — designed for exposed installation under the hood
• Complete mounting kit — steel bracket, bolts, nuts, and washers included

Mounting this dual trumpet horn on your car

First, identify a rigid support capable of withstanding vibrations: front crossmember, radiator support, or firewall. Mount the bracket, point the bells downward or forward so that water does not collect inside, then wire the relay between the fuse-protected battery and the horn. The original wire is then only used to activate the relay. This air horn installation remains accessible to a handy DIYer, but the size of the two bells requires checking the available space on your model before purchase.

Should you keep the original horn in addition to this one?

This is often the best solution. Many drivers keep the factory horn for everyday use in the city and operate the electric air horn via a separate button for situations where they really need to be heard. The installation is identical; you simply need to add a switch in the cabin to the relay control. This also prevents being startled by an accidental press in an underground parking lot.

Choosing your sound warning device from a car accessory specialist

An auxiliary horn is judged on three things: its tone, the sturdiness of the mounting plate, and the presence of the relay in the box. We rule out bare models, whose installation quickly turns into a headache. If you are hesitating between this 12 V dual trumpet horn and a more compact model that is easier to fit, our French-speaking team will guide you based on the space available under your hood.
