it wasnt that big of a deal for me at the time for me..it was a two piece box, when i was ready for it to come out i just had to take the box apart i will post some pictures of it if i can find some
what do you mean about cut an opening? i had a car very similer to the the on the OP mentioned and i had two ported L5's back in 2001 and i didnt have to cut anything
