I am in the process of installing 16 gauge wire to replace the factory door speaker wiring. I am stuck with routing the speaker wire through the existing rubber grommet. Specifically, there is a white plastic bulkhead that is blocking me. There are 2 of these bulkheads, one on the door end and the other on the cabin end. The door end simply popped off, but it seems the cabin end doesnt pop off as easily. Does anyone know how to pop this bulkhead off without breaking it?

Thanks
