Been thinking and browsing the web today while watching the gp, and found these...

How about those with on dash against the windscreen or in footwells (depending on size).
I don't think audio is really ever going to work well in a VX, but it could be a relatively cheap and simple install for some front end fill???

They may fit in holes at the end of the chassis beams (in the footwell) but I doubt it.
