Ive bought some air horns with 4 trumpets,the longest bieng about 8inches.Its looking tight under the bonnet,where has everyone else mounted thiers?

 

Mine are mounted behind the grill, in front of the radiator if that helps.

Dave.

 

4 trumpets behind front number plate,compressor in engine bay between battery and radiator.

 

Made a bracket that fits onto the battery retaining bits for the compressor and relay. Removed all the standard (and in my opinion, pathetic sounding) gubbings. Made another bracket that mounts onto the standard horn mounting between the radiator and the front grille and ran the tube through an access hole in the front left corner. I'll take some digi photos if you want?

Might be a newbie, but had 3 Imprezas over last 7 years, all with air horns.

 

I agree the standard horn is pathetic.Thanks for the info.
