2004 Carrera 911, new for me. I have the old speaker out, it has 3 holes for the screws not 4k which means it has a V shape outer foundation so to speak. They are Bose but I cant find anything that works. I think they call for 5 1/4 inch speaker but I measure it at closer to 4 1\2. Looking for help!
Thanks,

 

Are these forums just not active, I get no responses. Anyhow I removed the old speaker box from E Bay that has the normal speaker screw holes.
