I have recently had a custom box made for my d in a similar format. They were able to make a box that fits exactly on the shelf and extend at an angle toward the rear window. They were able to make the angle exactly as the cargo net sits as not to stretch it. They then put in 2 Kenwood 4 way 6x9 speakers and 2 10 inch Rockford Fosgate (spelling apology) subs in the box and placed the Alpine amp under the passenger seat. I had installed the matching Alpine receiver and cd changer installed previously. BTW the Alpine cd changer fits perfectly in our glove boxes with no modifications. The speakers and amp was mine from before so the total cost was about $125.00 installed and I have had several people ask if the box was factory as the carpet matches almost exactly. Email me directly for pictures.
