Ear Cannon Air Horn

Instructions and owners guides for many products can be downloaded from the Aerostich website at: www.aerostich.com/catalog-pdfs - the horn instructions can be directly found at this link: http://tank.aerostich.com/pdf/prod_guides/3830_3831_3837_Horns_rev0608.pdf

I think it is -- the last one I bought and installed sure was. So when my wife got a new car with a horn about as loud as a mouse's whisper I ordered this Cannon. Pleased as punch I was the day that I came up with an excuse for her to take my truck and leave the car with me, at the house, so I could install the horn when she wasn't around to ask what I was doing. But when I opened the package I found the horn, the wires and relay -- but no instructions. I can figure out the horn's + and - , but how about helping with a "pin-out" of the relay so I'd know which wire goes where? If it's in the package - it's well-hidden. Her car is still mewling and whispering but certainly not startling any but the most timid. What do I need to do to be told which goes where? Thanks.

Easy to hook up - very loud

Excellent and loud!!! Have it on my bmw gs adventure. Rain and heat have been no problem. Made my own bracket to mount on engine guard.

I bought one of these about a couple of years ago. It has saved my life more than once. I commute daily on the freeways in northern California and split lanes. When someone tries to encroach on you this horn will DEFINITELY MOVE THEM BACK! Instead of the wimpy stock horn that caused people to look around for that annoying squeak, this thing draws their attention, snaps them into consciousness and has them looking for the 18 wheeler!

I lost the first one and ordered a second. The intervening week was shear terror for me without the protection the horn affords. YOU must get this thing for your safety.

Note, on the latest one, I epoxied the bolt to the braket so that it cannot vibrate/slide out. I mounted it on my Triumph Scrambler on the original horn bracket, just skewed to the side a bit.

Purchased a couple of months ago. Sourced another company's horn/headlight modulator but went with Aerostich horn due to Aerostich's reutation for only selling quality products and great custormer service - a thing's only as good as the folks selling it. Anyway, had modulator and horn professionally installed as my BMW R1200ST made placement tricky. My mechanic found a spot underfairing on one side. The horn is freaking loud. Use with proper discretion. Tip: In a higher-risk-than-usual traffic environment, know how to get your thumb to that horn buttion fast without fumbling. Practice if you have to Those reaction fractions will - along with a kitten-crapping loud horn - will make the difference!

This is an impressively loud horn. It has to be 10 times louder than stock, and it's enough to make you flinch, especially if you honk it in the garage!

I had one of these on my 2007 Honda Shadow 750, but where I initially mounted it, there was some contact between the horn and the back of the front fender on hard stops. Eventually, the trumpet piece fell off somewhere on my commute. When I got a replacement a couple weeks ago, I mounted it on the left engine guardbar, clear from any contact. Had to fabricate a bracket that I attached to a highway peg clamp - too easy. I got the replacement just in time, as I was riding that first weekend through town and had an SUV try to change lanes on top of me. The blast made him drop his cell phone and he almost overcorrected into the oncoming traffic. Now I'm working on turning the compressor from the first cannon into a portable tire inflator....

I wanted a louder-than-stock horn and this is it. It was too big to fit on my 2001 Bonneville, but I was able to disassemble it and mount the compressor under my seat and the horn on the frame without too much trouble, see description here:

Installed this on my 2013 Moto Guzzi Stone. This horn is great. Very loud, and very easy to install with the plug and wiring harness. Now if I can only get someone to cut me off!
