If you're tired of the H3 toot. I'll tell you what I did to fix it. got a twin horn from a 2010 GMC Sierra 3/4 ton. GM part # 84501930. Plugs right in to my 2009 harness. I used the stock bracket, took off the single horn, and attached the horn assembly. Everything clears the grille and now it sounds like a truck.

 

On my 07 I used a Deluxe 4 Horn set from a 1971 Cadillac Eldorado.

Thanks for the tip with PN for a Horn Replacement.

 

Yeah, I've heard the Cadillac Eldorado horns are the bomb!

 

Thanks for the info. My stock horn is useless I was looking around for something else. Mine is an 07 so I'm sure the plug will be the same. Would you have a picture of them installed my any chance?

 

Cooter... Thanks again for the info. I did the install today. I ordered the horns from Amazon. The sound the new horns make is a huge upgrade the H3 should of came with them from the factory, not sure what someone was thinking adding that one small sounding horn.

As you can see I used the factory bracket to install the new horns on only needed to add a new bolt/nut and washers to hold them on.
