Does anyone have the specs as to what size speakers are in the doors / rear of the C230 made in 97?

Also, does anyone know if the amp was seperate or built into each speaker of the non-bose system.

I [Circuit City] installed a new JVC deck and it sounds like **** because I believe its conflicting with the factory amp. I don't know if I need to rip out all the speakers, or just have it re-wired.

Thanks
Evan
