I have a custom fiberglass box that will fit in the spare tire hole in a hard top for sure but I don't know about a drop top. It will hold an inverted 15" sub. I had a JL Audio W3v2 and will throw it in too. It worked fine when I took this all out, no rips in the suround or holes in the cone. I will get some pictures up tomorrow hopefully but I'd like around 250 for both. The speaker alone was 500 new and a custom fiberglass box is another 300 at least. You can contact me at ahall2004@yahoo.com or on here.. Like I said Ill put up pictures tomorrow hopefully.
