question, i am a noob at custom enclosures and now that i got my mdf work mastered i am getting into glass. i came across a set of new 12 audiobahn subs that i want to experiment with. i want to do a reverse sub set up in glass. i got the know how to lay glass, but how do you really dtermine the postion of the subs for the best sound ??? and how do you really get a specific dimension with all the curves you get from your trunk when you lay glass???? A LITTLE HELP !!!!!
