Q: Why I feel the sound of this air horn is low?

A: Step1: There is a difference between positive and negative poles in the wiring of the terminal under the air pump. Please check whether there is a reverse connection.

Step 2: Check if the harness(blue/white wire to your original horn wire) connected to the car device is loose

Q2: The manual of the air horn is hard to read?

We have improved the manual so that customer can read easily

Product stopped working the day after it was fitted.... Both air compressors are completely dead!Hope the replacements sent will last....Since I can't contact you directly and Amazon is making it impossible to have direct access to a REAL person to sort this out, I'm leaving my response here!As an international buyer, this is very concerning....Now I am expected to send the old Units back, at my expense! This is not happening....Sending it back again with DHL will cost the same as my original purchase.Amazon has my delivery address, you can arrange pickup on your own... I'm not paying for this to be sent back, and will also not be billed for the replacement units.Parts will be available for pick-up for the next 4 weeks.... Then it is going into the bin.

Difícil de instalar, pero después de todo si funciono, llego deteriorada, pero con la reparación ya funciono.

This horn is most definitely loud no arguing that! I'm just glad I had more connectors because every one of them that came with the wiring broke right off during install. Not a lot of length to the wires either, I had some of that I added to thr exsisting as well luckily. I would recommend having both on hand for the install. If you need to hook this to a switch instead of your horn jump your positive wire to your battery instead of the negative! Would recommend!

I purchased this to change my main horn on my car with. It was easy to install - just had to connect the car wiring to the horn relay and connect it all up. The hardest part was probably mounting the horn unit under the bonnet - I used the supplied clips and a good number of cable ties and it hasn't budged at all.Seems to be well made for the price of it and has been working well - it is quite loud! Not quite truck loud, but louder than a standard car horn.

If you’re looking for something other than a air horn with a tank and compressor n get ya close to that then this the best I’ve found so far.... it’s not a Kleinn but it’s also not 300ish.... if ya didn’t know the longer the trumpet the deeper it is... I believe this is 16.5” and anything over 16” is what anyone should be looking for.... the electric compressor seems a tad bigger than most your standard so I was alil skeptical at first but the sound isn’t so bad.... if ya know what you’re doing install is simple just get a momentary horn button.... install took about a hour n tht was just really looking for a location under the hood
