We purchased this horn to provide a louder replacement for the stock horn on our Mazda speed6. It did the trick. It has a unique but pleasant sound and roughly 50% louder than the pair of orginal horns. Installation was easy and horn appears to be well constructed. We have had it for about 3 months now with no problems. It is hidden inside a wheel well so can’t see if there is any corrosion but it is working fine. Overall a very good replacement or upgrade horn.

Willing to increase safety by installing a louder horn, this horn did the trick. The installation was simple and the horn outperforms the factory horn in my 87 Honda Magna; the dual tone sounds much nicer. Keep in mind that, as the manufacturer suggested, using the enclosed relay means that you will need to purchase 16-gauge wire to run the battery-to-horn circuit which will be activated by the motorcycle horn button.

I bought this product for installation on a motorcycle to replace the wimpy factory horn.

A nice product. Almost looks like a copy of the similar Stebel product with chromed plastic “horn” to direct the sound and dress the unit up some. “Some” being the important word. The chrome plactic cover on this product does not cover all the zinc steel body and leaves that zinc body and the ugly black plastic bottom very visible. The product being called CHROME infers that all visible parts are CHROMED and they are not. That is probably the only drawback of the product. Wiring was idiot proof with the wiring diagram and relay included. Needed items other than hand tools were some crimp on spade terminals and wire. The “mounting” point of this horn could also be a bit larger and include some type of chromed or stainless steel clamp or band for mounting to a motorcycle frame. The item is certainly priced right. I have a Stebel on another bike and as for noticeable volume/decibels difference between the 2, it is close but I think the Stebel may be a slight bit louder.
