When I first installed the horns they weren't loud at all. The compressor was very tight and hard and barely worked. They seemed very tight production wise. With no hose connected to the horn, I sprayed WD-40 onto the air intakes of the compressors and turned them on for a good 15 seconds to allow them to pump the WD-40 through the air pump. The pumps came off well and after reconnecting the air hoses to the horns these horns are incredibly loud, I'm very happy with them. I installed two of these in my RV and oh my god the next person who cuts me is going to have a nice noisy experience!
