Big stereo systems are nothing new, but when they are on the OUTSIDE of a luxury coach ...Well, that's different.
I heard this bus long before I saw it, and that was due to the at least 50 speakers mounted to the outside of it, including 6 subwoofers under the front windscreen. I'm not sure exactly why, but heh, it is kinda cool. The entire bus had been sprayed with murals and stickers. I managed to get a couple of pics and a short video (shot on my iPhone) to give you some indication of the monstrous sound.
