Depending on the size of the speakers (i.e., around 6 inches in diameter),
mounting them
on the rear side panels is not really a problem. Those cardboard pieces don't
have a
lot of strength, but enough for this purpose.
As for fitting covers to the backs of the speakers, Joe, I believe this would
only
reduce their effiency. Speaker cones vibrate on two sides -- the front and the
back.
Enclosing the back is fine, as long as your create a port on the front mounting
surface
so as to relieve the back pressure -- i.e., "sound" -- coming from the backside
of the
speaker cone.
More to the point -- it don't hardly make no damn difference when you driving
with the
top down, the tailpipe blaring, and the rattles rattlin'.
