Review on 🚚 Enhanced Safety with the Marco Xtreme Blast Electric Horn - Italian Truck Accessories | Ultra-Loud Car Horn at 120 dB | Dual Compressor for Improved Performance by Joe Roberts

The horn is loud with a great tone, not loud but definitely louder than any good standard horn. Tested them directly with a shop compressor and they sound very loud at only 20-30psi. The problem is the relays are cheap and fail after 5 or 6 simple siren activations. I would have liked better components. Installed in the Mazda CX5 on the front corner between the fender and the radiator area below. I mounted the compressors on a homemade bracket in the same place, hanging both compressors at an angle and then down into the well. I installed the relay on another corner that was attached to the battery holders.
