Okay...what you do...measure you the opening you want to cover (the place where your box is...to the fenders of the car there.) and build a board that exact size..cut out the speaker holes in the proper part of the cover board..carpet it, and attach it with screws (under carpet of course), or you could use double sided tape to attatch the cover board. Then do the same thing for the amp, but make its cover board extend to the sub box..if you have any more questions feel free to ask. or talk on messenger. (clay_rhye54@hotmail.com).
