Wolo(845) Road Warrior DD Roof mount Truck Air Horn - 12 Volt

This horn is a good purchase for between 50-70 dollars. The box arrived quickly and in good shape. It included the correct product, instruction manual and some mounting hardware. Note: if you are intending to mount this horn in any other way than intended be cautioned that it is very large. I didn't want to make it visible and found that it fit well under the rear bumper of my vehicle. Took very little time to install, instructions are straightforward and all the required hardware was included (except drill bits). The horn is very loud and works well. The compressor takes about 1/4th of a second to generate pressure from the time the button is pushed. I recommend buying a better switch to use though, i bought a switch at a local hardware store for less than a dollar which works much better than the included one. Wiring diagram is complete and wiring is very simple.

Works great, sounds great. Installation was a pain for me (it's under my truck) but that's no fault of the product. I did go with the bigger compressor as someone else suggested, NOT sure I needed it though

Horn worked fine but compressor was bad. Contacted Wolo. They said at first to pay them $10.00 and shipping and they would check it. That would have been about $20.00. I ordered a compressor form another supplier f0r $16.00. Everything works now. After that I received an email saying they would waive the $10.00. That was nice but way too late. Should have been checked before shipment.

Put this on a 2004 Mazda 6 (had to use some southern ingenuity L brackets zip ties hose clamps and a strong desire to succeed) as I did wired it to a push button away from my main horn this way my wife can still have her horn an wether I'm driving or in the passenger seat I can blast it at any time! I love my air horn! I will also mention I did also wire an older wolo model 110 boat horn I had bought a while back for an e bike I rigged up... It has a slightly higher e pitch but sounds great with the two horns in tandem!

After trying to find a spot to mount, not on roof, I finally had it working with stock horns. Seems the stock horns are just as loud.

I thought it was great at first, then within about five weeks it broke and couldn't be fixed. I contacted the company to see if there'd be an easy exchange solution or if they could send me replacement, but they advised me to go through the warranty procedures. However, the warranty procedures were useless because the horn and compressor were already installed and it would've cost more in labor than the value of the entire horn just to detach and mail them back. Ergo, I'm left with an installed airhorn that doesn't work at all.

this horn is big but it is definitely not loud, very deep sound but my stock horn is louder. might need a bigger compressor.
