i put an omega twin horn on my corsa b, took the old one off, the new fits in easy enuf ust a case of makin a lil wiring so you can put it from one conector into two, i just bridged two from the one positive and plugged them on and the same with negative, took 5 mins, sounds harder than what it is

calibra ones sound quite good. guess cav would be just the same.

i've got one to put on mine if i ever get round to it.
think i read that you need a relay for it or something, cos the standard wiring too it won't provide enough juice.

air horn attach a dump valve to it.. and uve got he best horn ever :lol:

I got an air-horn from Halfords, but found it sounded too high-pitched, so left the original one connected too, sounds quite good.

that what i did

i had the same problem the other day...
i got a calibra horn and tried to fit it to the corsa but i couldnt reach it!!!
so if i undo these bolts at the top of the bumper i'll b ok???

i fitted an airhorn to mine,

just pulled wires off existing horn and stuck em onto new one, was piss easy.

can get to the old horn by un-bolting just the top of bumper and pulling it forward

Is it easy to remove the original horn???

I've heard you've got to take off the bumper to get to it

yes i think the higher ones are 2 tone so there is a little bodgery involved

failing that get a air horn jobbie from halfords

Now that I have your attention the horn in my car is pathetic and I was wondering how easy it is to replace it with another one off of a vectra or some type of air horn set up, anyone changed they'res and if so what kind did they use???
