These horns are designed for durability, easy fit, and extreme sound.  The ABS trumpets with extra-wide bells produce a bone rattling locomotive blast that can be felt as well as heard.  This kit includes a 100% duty cycle compressor that delivers the 150 psi pressure you need to get maximum output from your horns with only a minimum of space. Perfect for frame rail mounting in almost any car! Includes 5 gallon tank. Quick refill a time, only 21 seconds to recharge.  The compressor is sealed and moisture/dust resistant which means mounting on the underside of a vehicle is no problem.  The system also includes a remote intake filter and check valve to prolong the life of the compressor.  High output minimizes the time it take to recharge the tank. Included with the package is an installation kit hooking up the compressor and a push button switch for activating the horn

Professional installation recommended.
