You're probably going to loose quite a bit of room in the boot with 2x12's! A single 10" sounds pretty good, I have to say. More than enough bass for me, at least.

Cambscar built the box & did the whole install. The front speakers were (and still are, I didn't bother removing them as it'd be a major hassle) Infinity Kappas. Very nice sound, the beetle appears to have excellent speaker placement and general accoustics.
