Hey Brian just pop down to REPCO and buy the cheapest dual air horn kit they have - probably less than $30.

When you fit it just use the shorter of the two trumpets - this is the higher pitched one. Two reasons for doing this - one, it will be much louder when the air produced from a compressor designed to blow two trumpets is all fed through one, especially the shorter one as it takes less air pressure to activate; and two, it is easier for the listener (the dickhead you are horning) to determine from which direction the sound is coming. Low pitched sounds, like the fog horns on a boat or the long trumpets on a semi for instance give noise that appears to the listener to come from all directions.

Mount the horn behind your left hand fog light on the frame of the car that runs forward to the bumper - easy to access once you have the stone undertray removed. Mount the compressor as close to the trumpet as possible. Use a good quality relay so the power is taken from the battery and not the piddling little wires that Ford use for their horn. Just unplug the +ive wires from the existing horns - use one of the +ive ones as your switching wire for your relay.

Or just come down for a drive and I'll do it for you one weekend mate. Time you and Joyce had a nice relaxing weekend down the South Coast isn't it?

Ok I took a couple of small vids. 1 from incar, the other I had my phone sitting ontop of the horn under the bonnet. I couldnt blast it for too long as my elderly neighbours came out after the first go :fool:

I got an air horn off ebay for $79. it's 134 decibels, and is like a train horn.... BLOODY LOUD... very useful for roundabouts with the idiots who don't care if you're on it.......

took half an hour to fit, and did not take up much space....

I agree the horn on these things is real ordinary. Been thinking of doing the same thing and found these.

I found out recently that the horns on the B series cars have gotten worse since BA1. Mine is fine so I thought nothing of it, but Ford made cost changes to BA2 and with BF and BF2 it's gotten even worse, the horns are nothing like the originals. Seems like a bad place to cheapen out.
