For a possible workaround, try using the variable %z instead of x; thus
(%i13) f1 : convolution(unit_box(%z),unit_box(%z),%z);
(%o13) (%z*signum(%z))/2-%z*signum(%z-1)+signum(%z-1)+(%z*signum
(%z-2))/2-signum(%z-2)
(%i14) f2 : convolution(f1,f1,%z)$
(%i15) f3 : convolution(f2,f2,%z)$
(%i16) plot2d([f1,f2,f3],[%z,0,15]);
