GAMPRO 12V 150db Air Horn, Chrome Zinc Dual Trumpet Air Horn with Compressor for Any 12V Vehicles Trucks Lorrys Trains Boats Cars Vans (silver)

Very loud and great two-tone sound.Both horns sound together as this is a legal requirement.Very easy to fit as all connections are supplied with connectors and even a relay socket for the mandatory relay which is supplied as an 80amp version so hopefully will easily handle the current.Wiring instructions OK but the coloured picture from the Internet on the Amazon site was more useful, see the wiring instruction thumbnail 4th from top at left side of page: https://www.amazon.co.uk/dp/B07H85VRSR/ref=asc_df_B07H85VRSR58615499/?tag=googshopuk-21&creative=22122&creativeASIN=B07H85VRSR&linkCode=df0&hvadid=310764720204&hvpos=1o1&hvnetw=g&hvrand=14027650349674052822&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9046988&hvtargid=pla-633370679426Remember the polarity for the compressor as if wired the wrong way round i.e. wrong polarity the air compressor will suck and not blow the trumpets. Only problem is mine arrived without the air hose but as I was replacing an old air broken horn, not GAMPRO, I used this tubing which fitted perfectly. I would have given 5 stars and not 4 if air hose was not missing.

The air compressor packed up after a hand full of times.

Exceeded my expectations on the physical use of it. However the installation process was such a pain. The positive wire is good because it’s so long, but the negative wire must be 15cm tops, then the wire to horn (blue) is again the same length. So it’s very hard to find a good spot to put it. In the end I just stripped some old wire and wired it myself, this works really well.4/5 because of short wires.

Used in my be camper the old horn wasn’t very good now sounds great

These horns sound great, made me laugh the first time I heard them.Pity that a bit more care wasn't taken in the packing of them.The air pump motor ( quite heavy in relation to horns) was sandwiched inbetween and on top of the metal horns. The photo shows the damage caused by this action.Also the motor had obviously been dropped onto a hard floor prior to packaging, as it to shows signs of damage. It's packaging was unscathed.As the horns are not going to be on show and the pump works, not to bothered about it.But it was a shame a little more care wasn't taken in the packing of this product.Still great sound......Edit.....problem solved by Elle at Gampro....many thanks..new horn...still smiling

This was excellent at first but its only been on the car a couple of weeks and already the large trumpet has stopped working, it sounds pretty lame with just the small one and I really cant be bothered to strip it out of the car. Their is zero chance of water ingress into the trumpets, I have them firing directly down. Sometimes the big one comes on but mostly not. The compressor is mounted very close and the tube is very short.Edit:I cant fault this company, they replaced the horn and its now perfect, I will also say I did not have to extend any cables, everything that was needed was included, I highly recommend this product, it sounds fantastic and very loud.

I enjoyed wiring and fitting this into my car, very simple. However I do find that over 70% of the time it'll go high pitched and not low. It is loud however probably not the 150db quoted.

There was no wiring or compressor in the box
