Well, I think the time has come to replace my rear speakers...but I don't know much as far as sound systems go or speakers, so I've got some questions. Will a regular 6" mid fit into this space? Is what I'm looking at back there a speaker cover or the actual speaker? I'm thinking I want to put two JL 6's in place of factory, but I want it to look flush and not all hacked apart. If anyone has any info they can give me or atleast pics of their back speakers (NOT SUBS), that would be awesome.

I've got a 92 GS.
