Easy to install. Pretty loud first second, than noise goes little down.In general for this money is good product)Make sure you install separate switch for compressor, otherwise if you don’t start the car, it will sock out the battery pretty fast)
Nice small set up, wasn’t expecting a lot more as a joke on my truck. Came in and easy to set up! Wired thing is horns will not work when air tank is at full psi only work 75-0 nothen higher. Seams weird to me but not bad little horn and such
