The center speaker on the dash of the GS430, is that strictly for the navigation?

I have just purchase a 2001 navi, computer, ML amp, with wiring harness looking to do a system change in my GS400. Was wondering what sounds come out of the dash speaker.

Thanks

 

Thats the center channel of the ML system. Has nothing to do with the navigation. Voice for navigation comes out the driver side speaker I think. You threw me off the 2001 GS400, but I know you mean the 430. U going to do what? You don't like the sound out of the ML? Let me know I might want to take some of the speakers off you for spares. Or the ML AMP.

 

I would hate to cut a hole in my dash for that speaker, has anyone mounted one in a different area?
