Review on 🚗 Enhance Your Vehicle's Sound with the MPC B1 (0419) 4 Trumpet Train Air Horn Kit - Perfect for Trucks, Cars, Jeeps & SUVs! by Joe Fulce

Easy installation but I recommend dry installation on the car to check function and tightness. I did not find anything about this device, but the previous one from another brand was garbage, and dry landing saved me from a lot of aggregates. The biggest challenge was finding the right spots to mount the pipes and tank, but after some modifications to the 18 Silverado's spare battery compartment, it was all pretty easy. Also, I took feedback from other users and bought a Kleinn pressure switch and a pipe magnet and made sure all the fittings were tight and properly sealed. I disconnected the compressor from the relay and the pipes from the relay for two separate switches. One to turn the compressor on/off and one to operate the horn solenoid. A little extra planning made the end result worth it. The only reason for 4 stars is the sound quality. Although the sound is extremely loud and perfectly equipped, it is more in the upper middle range. It doesn't have exactly the low notes I was looking for, but in the future I might just buy a set of Kleinn whistles and leave everything else, or replace the bells and remove the high notes and get all the low notes (keep the last few broken blocks , since the seller does not want to return, again another brand, but the whistles are fine).
