Theses wires?
 

Hello, 2000 base. Trying to get some music going again. Looking what PO did. I know the wires on right are speaker. but what about the other 2 and black connecter? Also. I changed the door and dash speakers, seems like door don't put out as much power. Any reason? Thanks for all your help!!http://986forum.com/forums/uploads02...1570746033.jpg

Looks like the plug for the cd changer

Or the external amp.
