You mean for behind the rear seats? It really isn't that hard to make one yourself. Just get a sheet of mdf, some brackets and some carpet. Measure twice, cut once and itll come out fine, for a fraction of the cost
Otherwise keep an eye on ebay and one might pop up
Just get a car audio store to make one... As far as I know, it's not a premade item that you can buy. You'd probably just be buying a second hand one from eBay.
