Need help with mounting siren speaker

[Butrum10]

I have a 2012 nissan xterra and i had the siren mounted directly in front of the radiator which was causing the radiator to get warmer than usual. So now my question is where would be a better place to mount it there is no room under the hood and all my openings in my bumpers have oil coolers so where would be a good place to mount it so i could get full use and sound from the speaker. Also the speaker is a whelen sa314

Remove the plastic shield (sound director) from speaker and radiator should be fine. Volume will not be affected
