I had a custom box made for my beetle... if you're in the UK it's possible I could sell it to you

It fits in the left side of the boot, and takes a phase linear 10" sub (which doesn't need much box volume). I've even got a carpeted amp mount which fits onto the rear of the seat... makes installation much easier, these two cost quite a bit to have made but I didn't want to sacrifice boot space. Pics on riocar.org, but I'm using the "active" components (ie, the actual sub and the amp) in my honda install so I'm just looking to sell the woodwork.

Of course, if you're in the UK you could buy the car too... 9,995 for a genuine UK-sourced 2000V techno blue bug with leather interior, 23k miles, FSH.
