 "D8-1 top view out of the car.")
This is a box we make called the D8-1. It fits on the Rear shelf behind the back seat in all 996 type Porsche® Coupes and Targas. It also fits in the '05 Coupes. made with 4 layers of 2oz mat with no flat sides, and extra thickness in the baffle area. Stiffened on the front side and with cross bracing on the baffle. It fits most stamped basket 8's with a magnet diameter of 5-1/2", like JL and Kicker.
 "GT-2 box not installed.")
This is the shelf on a GT-2®. No back seat but the sheet metal and carpet are the same as all the vehicles that have a Bose® sub box. When the box is in a car with a back seat you can't see it from the driver's seat. it is flush with the lip on the back of the seat. You can just barely see it in the mirror.
 "Box in the car no carpet.")
This is what it looks like in the car (the GT-2®). We sell it "bare" with only the grill so we can sell it cheap. If you want we can supply it with original Porsche® carpet and cover the grill. Internal volume is "as big as we can make it," about .75'.
 "This is what it looks like in the car with the carpeting.")
We paint it with hi-fill polyprimer so with a little prep it could be painted body color or covered with leather, vinyl or whatever. We don't supply any mounting hardware so you have to figure that out for yourself. We make a mdf plate that sits on top of the ECM cover, then we run a couple of screws down through the speaker hole into that (this mounting survived a rollover intact.) I'm sure you can come up with a better way.
