How can i model this shape?

[system]

Hello everyone, I’m trying to model this radio for practice:

In Cinema 4d I started drawing a spline from the top view, and then extruded up, the problem that I’m having is with the back of the radio (marked with red circle), I imported the basic mesh to zbrush but Im having troubles with that back curve, any suggestions?

Thanks for reading, any tip is welcome

well you gotta think in 3d, not 2d. i personally woul just model it using polygons as you can get the exact shape you want then bring it into zbrush and polish it so that those shapes are visible. if you have 4R5 you can use panel loops for the 2 plane groups that make up that radio
