#205446 i hate my weak ass stock horn and i have a horn from a gmc sierra. Whenever i hook it up and try it it wont honk loud, you can bearly hear a low sound, like if it wasnt getting enough power to it. Anybody know how i can get it to work properly? and if its possible i want to put both of the truck horns on :? lol

#216865 some of the trucks had a high and low horn aka 2 horns total!!!

you may also need the second horn or it will sound funny if it's high low horn set up!!
