Also, the Zeo Power Chamber couldn't have been destroyed with the Command Center, since it was the destruction of the Command Center that led them TO the Zeo Power Chamber. To answer the question, I view it this way and you can take it how you will: Command Center was destroyed so they moved to the Zeo Power Chamber that was built below it (as seen in the first episode of Zeo). However, the Turbo Power Chamber was back on the surface, as shown in Chase into Space. It is very possible that the Zeo Power Chamber still exists, and thus the Zeo Crystal, however it has not been definitively shown whether or not it was destroyed. We do know the Zeo powers were rendered obsolete during the Turbo movie.

Furthermore, the Morphing Grid still works to its fullest as it is the source of every team's powers since MMPR. You probably intended to reference the Zeo Crystal's connection to the Grid, and since the crystal was never seen destroyed it can be assumed it is still functional. Whether adequate or not is another story.
