Well here it is big and loud. This thing is MASSIVE, i wasnt expecting it to be this big but the size makes up for the sound. It sounds just like a real train horn and i tested it in a wide open area where there are nothing but fields and the echo this thing gives off is just out of this world! Anyways ill get a video of it at the same place i tested it when i got the good echo. I cant wait to get it on my truck!!! :D :D :D
