Vanquish horn upgrade

[V12Vanquish]

I think the stock horn on my Vanquish is rather puny, more in keeping with a Fiat Panda or such like. I would like to upgrade to something a bit more upmarket and befitting of an Aston (louder is better). I have several previously used options available to me from my parts bins and there is plenty of room in front of the radiator to fit something better.

To save me a lot of investigating of the electrical box under the passenger floor etc, my question is does anyone know for sure if the stock horns are already wired through a relay and where it's located, so that I can just install some better quality horns in place of the originals. I'm competent enough to wire an additional relay to carry the extra current, but may not need to.

Any helpful advice appreciated.

If you are replacing with standard horns, they will be fine on the current relay.

If you are putting in a Dukes of Hazzard stylee compressor, you may need to upgrade the relay - and the paint job..
