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 Kevin Mills

***UPDATE*** Dead after 16 months. Contacts on 1 compressor are rusted and the compressor does not work. Relays are intermittent. I contacted the seller, they said the warranty is 1 year. So basically you're gone. The sound is amazing. Not too loud, but definitely better than factory. The installation takes some time. I paid to have it installed by a reliable mechanic. It took two of them 2 hours to install it, implicitly following the instructions. The compressors run immediately even if the alarm is activated.
