Worlds Loudest wine barrel Thumbs up First ever hand flex video at 6:20 Demo at wheel kings, lots of flex, shield, car, and hands DD audio 9512i supercharged on a crescendo bc3500d in a wine barrel, This was the day I put it in and went to show my friends the results. I had not started to sound deaden, which is why the lisence plate makes some noise. So if you like to complain about rattling, this is still an ongoing work in progress. Everything will be done proper.
