HELLA HKA Twin Trumpet Air Horn Kit, 12V
HELLA HKA Twin Trumpet Air Horn Kit, 12V — Product description
The HELLA HKA twin trumpet air horn kit delivers a loud, dual-tone blast from two trumpets tuned to 780 and 840 Hertz. It runs on 12 volts and ships as a complete kit with compressor, relay, tubing, and mounting brackets.
The HELLA HKA twin trumpet air horn kit gives your boat or truck a loud, dual-tone blast that people actually hear over traffic and wind. Two trumpets, one tuned to 780 Hertz and the other to 840 Hertz, blend into that classic deep, layered note. It runs on a standard 12-volt system, so it wires into most rigs without any special hardware.
This is the complete kit. You get the twin trumpets, the compressor that drives them, the relay, the tubing, and the mounting brackets, so you're not hunting down extra parts after the box shows up. The trumpets are molded plastic with a painted red finish, which keeps the weight down and holds up to weather better than bare metal.
Mount the compressor somewhere dry and protected, run the tubing to the trumpets, wire the relay to your horn button, and you're set. It's a straightforward afternoon install for anyone comfortable with basic 12-volt wiring. Great upgrade for when the factory horn just isn't cutting it.
