I bought this kit for my car
http://www.pbmissions.com/p8-Maximus-Horns-Level-4-Kit-180dB.html
Its installed and working its just not that loud, my compressor is shutting off at 115psi and the tanks pressure gage goes up to 160 with no red waring indicators. I was wondering what I would need to do to keep the compressor going so i hit a higher psi level and hopefully a louder horn.
Any help is appreciated thanks in advance.
well your air compresser probly has a pressur switch for 115. i would say get a different compresser. the viair is a damn good compresser.
bty for the amount you paid for that you should of gotten a shocker kit. it would sound so much better…
Personal opinion… 
Your pressure switch must be faulty or compressor is only rated to 115psi…or vise versa. What kind of company throws a 160psi gauge on a 200psi kit? Did every accesory come from the kit in the link?
Yea everything shown in the photo I received. I contacted the manufacture and they gave me instructions to change the psi on the regulator solenoid. But the instructions say I shouldn’t take the psi any higher than 120psi… any thoughts?
