This has been sitting around for about 5 years after I sold my z. It's a driver-side sub box that was part of DVFlyer setup. I tried looking for a picture of it installed but wasn't able to find one and will add it if I find one.

The stock foam pieces need to come out. The spare needs to be removed and the carpet needs to be cut or you could make a different floor that follows the contour of the box.

$100 and local pickup only in the San Jose area.
