I measured it today, it will not fit either getting inside or for say if I did get it inside it still would not fit right. and for the carbon fiber, I made my mdf box routes out my holes for the subs, then laid my carbon fiber on the face of the box wet and then rolled it out numerous times with epoxy. then built it up, block sanded it, then wet sanded it. finally cleared it with some ppg shopline clear. once it gassed out I went over it with 3000 on the da and used 3M's compounds 1,2 and 3. and you'll end up with thatClose. Measure it. How's u do the carbon fiber?
