Pressure switch question

Running a k3la and 4 shockers currently on a 10 gallon tank at 150 psi all seven horns going off at the same time.would my system b louder if I bumped it up 2 200 psi or should I leave it alone ?

Bump it up to 200 psi and regulate it to 140 or 150 to the horns. Anything higher will trash your diaphragms in the horns.

Higher pressure may make them louder but not only can it cause damage it can distort the sound.

Thanks allot guys ill probly leave it alone its plenty loud enough lol next project 98 buick regal gs havent decided what horn to use yet but there is a but load of room underneath the car lol let the fun begin
