I just got done screwing on the top of my wo and tried it out. Holy sh*t! I know you guys said it would be louder but I wasnt expecting it to make my ears bleed. What a differents. It was loud before but now its just silly. I had it in a 2cu. ft. sealed box before and it would shake the mirrors and the dash but now I have windows and quarter panels flexing, at a lot less volume. I still need to fine tune it and seal it up, just screwed the top on to try it. Im sure it will sound even better once its sealed.
