It's a Nissan sedan, the parcel shelf has cutouts in
the steel for the original speakers which suit the 6"
Kenwoods.
It also has a fabric covered composite board insert
over the steel shelf.
I thouhjt I could make some MDF boxes and mount them
on top of the shelf, but if that doesn't reduce the
distortion it will be a waste of time.

So is it worth making the boxes?
I was thinking 12mm MDF, and paint them matt black.
