I did not make the box for the car - everything was made by a company up in Kentucky - I am no carpenter.

Nothing is fiberglassed onto the car at all, I am not sure on the dimensions of the box for the subs.. its not as big as it looks on the pictures, the cover makes it seem like its a humongous box down there.

If any of you have any other recommendations to take it to get tuned I'd gladly appreciate it. Right now I cannot turn it up withut it distorting - They even said themselves it would sound serious once its tuned and good to go... I'd like to get into competitions and what not with the system if possible
