Description

● Sound Level: 150 dB ● Material Science:Zinc copper Aluminum ● Use For : any 12V vehicle,like most truck, train, van, pickup, car, boat, yacht, jeep, bus, etc. Durable Chrome-Plated Zinc Trumpets for Long-Lasting Use Used to connect the air compressor to make the sound emitted by the horn louder and more stable The integrated base is directly connected to 2 horn tubes for easy installation Harness with relay safeguards your factory wiring by routing high current directly from the battery, avoiding overload on original vehicle circuits. Q1: Is this 180dB train horn allowed for daily on-road use? A: It is designed for traffic safety alert. Please comply with local noise control regulations. Avoid unnecessary honking in residential areas. Q2: My air horn stopped working after a while. Is it broken? A: This is normal for high-power air horns, not a failure. Tiny particles may temporarily block the compressors during prolonged use. Disconnect, cool down, tap gently or blow the intake with compressed air to clear it. Avoid continuous long use. Q3: Do I need large space under the hood to fit these four trumpets and compressor? A: The 4-trumpet set has a certain overall volume. Please measure your available under-hood or chassis mounting space before purchase. It is widely compatible with trucks, pickups, RVs and off-road vehicles with adequate installation space. Q4: Why does my horn sometimes have delayed sound or weak output after installation? A: This is usually caused by loose wiring connections or improper mounting. Please double check all wire terminals and make sure compressors are secured firmly. Refer to the wiring diagram for troubleshooting. Q5: Will the loud air horn damage my car’s original electrical system? A: It comes with a complete heavy duty wiring harness to protect your stock circuit. When installed following the included instructions, it will not harm your factory electrical system.

This kit will surprise you I promise!
Set name: 2 compressors without button
I know these aren't anything like some of the hiring train horn setups on a truck with a tank and an air compressor and all that but for somebody that could just strap it on to their little bitty Prius and sound just like a train and it's very loud for what it is it's got two of these air pumps that move some wind I'm from the construction lifestyle and these little guys are extreme so one pump Powers a set of two horns and the other pump Powers the other set of two horns and you will you will see what I'm talking about when you put the kit together. ... show more

Well worth the money
Set name: 2 compressors without button
I put this on my 2012 silverado. 4.8l work truck had to modify the brackets a little by taking them off the bracket and using self tappers to drill them on to my frame in the photo. VERRY LOUD verry happy. I wired it to the toottoot horn wires by splicing the kit harness into my stock horn wires. DO NOT ATTEMPT THIS IF YOU HAVE NO ELECTRICAL KNOWLEDGE. now for a review with a sound clip. ... show more
