This is subwoofer in a custom sealed enclosure that fits in the area just behind the driver door on a 1978 40 series. It will fit other years as well, but probably not very early ones. It is a snug fit and I had it attached just with stick on velcro strips and it was really solid. It really helped with the making the sound system sound not so tinny. You will need an amp.
I will ship it for whatever actual shipping charges are.
