Place the panel without loudspeakers and grill on the door lining and align it:
Reference points for fitting:
Only precise alignment of the panel with the door
lining warrants optimal fit.
Reference line 1: the lower edge of the panel is parallel
to the lower edge of the door lining. (see fig.2)
Reference line 2: the front edge of the panel must be inline with
the design line of the door lining.
end of panel is in line with the door lining

panel edge and lateral
edge of the design line
are in line
