Custom Sub Boxes

I have seen in several magazines custom speaker boxes for the new eclipses. Are these things u can buy or are they home design and built items?

Thanks

I don't know if you are still around and reading this, so I'll post a response =P I have a 2003 eclipse, and I couldn't find any custom boxes. I made my own out of fiberglass, form fit into the corner. You can sort of see the sub in the pics here

But I don't have a pic of the sub in the light at the moment. It's form fit into the right corner of the trunk, and then carpeted. The way it's setup, it looks like it came with the car. Eventually I'll stop being lazy and I'll update my pics =P
