Review on 🔊 FIAMM 66040 Big Boss 2 Long Trumpet Horns with HVY Duty 12V Compressor Kit (10 Pack) - Powerful Sound Amplification for Enhanced Safety and Performance by Nick Andep

This is a great value for money air horn kit. I say softly because it doesn't sound like a real train horn at all. and cheap plastic pipes. As such, I would not attach them to the outside of a car that is going off-road where limbs or hands may meet. But they are good over the grill. They make a nice two tone big truck sound as opposed to small shrill kits. They come with two pipes, a compressor, a relay, a Y-pipe and a transparent air hose. There are a few things you need to know about this type of horn system. First, you need some space to install it. The tubes are about a foot long and take up some space. Also, you need to install them facing down so water doesn't get in and ruin them. If you don't point them down, they will have a short life. I've experienced this several times with other sets. Consider these thoughts and do not order this product if you cannot accommodate them. Also, have someone install it if you don't understand how a relay works or are familiar with simple hand tools. See [.] if you need help with the relay. Pin 30 goes to the battery positive terminal. Pin 87 goes to the horns. Contact 86 closes to ground. The original horn goes to pin 85. I think the compressor needs ground too. But that's all for the electrical part if you already have a working horn under the hood.
