🚚 Enhanced Safety with the Marco Xtreme Blast Electric Horn - Italian Truck Accessories | Ultra-Loud Car Horn at 120 dB | Dual Compressor for Improved Performance Review

Just in case anyone is interested the AMP draw is 20A for each compressor so you will definitely need 2 relays and at least 12ga wire for each horn require. Just installed so no idea on durability but it's loud and looks good. I love it so far!

***UPDATE*** Dead after 16 months. Contacts on 1 compressor are rusted and the compressor does not work. Relays are intermittent. I contacted the seller, they said the warranty is 1 year. So basically you're gone. The sound is amazing. Not too loud, but definitely better than factory. The installation takes some time. I paid to have it installed by a reliable mechanic. It took two of them 2 hours to install it, implicitly following the instructions. The compressors run immediately even if the…

It was a total of 24 days in my new F150 when it stopped working. I paid a reputable shop to install this horn as it was a hassle to install. The contacts on both mini compressors are rusted and both sides are corroded - see photo. This is a product imported from Italy without after-sales service or spare parts. Revain will not replace the device. Revain refunded my money BUT I didn't spend the time or money to install it. Now I have to start again. This horn has been good for 24 days but the…

The horn is loud with a great tone, not loud but definitely louder than any good standard horn. Tested them directly with a shop compressor and they sound very loud at only 20-30psi. The problem is the relays are cheap and fail after 5 or 6 simple siren activations. I would have liked better components. Installed in the Mazda CX5 on the front corner between the fender and the radiator area below. I mounted the compressors on a homemade bracket in the same place, hanging both compressors at an…

This horn is amazing. If someone interrupts me or acts like a jackass, I want them to hear my frustration. And boy - they ever can. Installation on my Ford Explorer took 6 hours - we had to remove one side of the bumper and install under the all metal bumper. It certainly doesn't take nearly as long with any other vehicle. This whistle sounds like a small freight train - and I'm in love! You need a wiring harness with a button - I had to buy a wiring harness with a switch for the horn. we…

This thing is LOUD! It's probably not as noisy as a 3 or 4-pipe system with a large air reservoir, but unless you're trying to get your neighbors to wet your bed, it should be sufficient for most people. It definitely scared my daughter's cat. It's a 3 out of 5 on my personal difficulty scale. Installation took about 2 hours. There is a large piece of cable to run and I had to make a bracket for the pipes. Unless you know what a relay does or how to read a simple circuit, you'll have a hard…

was installed on the late model F150. Standard horn measured 95 dB in manual mode. These horns produce a solid, repeatable 117 dB. It's about as loud as a gunshot. You don't have to run a lot of hose to the speaker and the compressors have to be mounted vertically. Pipes are less than 18 inches long (estimated), so take this into account when installing. It looks like a dump truck or some other big truck. This is effective for drawing the attention of inattentive drivers to the mobile phone…

The horn on my truck buzzed every time I locked it by pressing the key fob button once and the dealer said it couldn't be changed to my truck model (RAM - Express 2012). I live in a large apartment building and people don't appreciate it when they come in late and honk their horns, so I decided to do a clean install. I pulled the fuse on the truck's horn system and connected the horn button to these horns and they are amazing! The truck no longer honks when I lock it, but when I press the new…

Just opened the box and found the mounting base is plastic. Not quite sure how long this will last weather dependent. No mounts for air compressors. The calls are ok, some metal, I don't know the sound yet. Will be updated after installation. Update November 7, 2018 Just installed the horns. I play an 18 wheeler for a living, wasn't expecting the sound of a big truck. They are ok, good sound, not much volume. They are better than stock horns on my Dodge 2500 Ram. These horns sound like you're…
