hihosilva- hey nice clean install. good job.

i usually fire mine downward in front of the radiator for
maximum sound, but that far into the engine
room i think you can make if face forward like yours.

it might sound louder inside that cabin than outside, but
heck it'll still sound good.

 

i actually installed a triple trumpet air horn (sorry, no pics) using the original horn mounting hole as the mounting hole for the compressor, and have the three trumpets in front of the radiator but below the grill so you cant see the 3 red plastic horns. damn loud, too. my girlfriend gets embarassed every time i click my door lock button on my remote twice. fairly simple, except you have to bend the mounting bracket a little bit that comes with the new horn. like i said, damn loud, though.

 

Hella sells a horn set that is real loud.
