200QT Speaker Replacement

[jason@tgl.com]

     While I had the panels off my 91' 200QT doors, I noticed that it 
     looked farily simple to relace/upgrade the factory Bose Speakers. I've 
     already switched out the deck and added a Sony deck and changer and 
     had to bypass the amplifiers located at each speaker for my troubles. 
     Now I have to replace speakers because of Ohm setup. Has anyone 
     changed out these speakers and know what size/brand would fit in the 
     factory openings. Keep in mind there is a large molded area in each 
     door holding the current Bose Speaker amp setup. Suggestions please, 
     no time to check out the archives. Thanks to all...
