You might try the sequential fitting option of the "fitmap" command. After it fits one structure, it removes the density from that part of the map before fitting the next. Details here including link to an example video:

While using the fitting tool, I can get the atomic structure of the bigger protein docked very well, the problem arises while fitting the smaller one. The fit option fails and docks the structure into the region of the density map where the atomic structure of the larger protein is docked , an incorrect position.
