I have a nice set of 6.5" Coaxial Blaupunkts I picked up at a clearance sale a while ago. They fit perfectly next to the sun visors in the headliner area, they just need holes in the liner and mounting brackets, and the wires can be run up the windshield posts. I like speakers in that position, but then I have some high frequency hearing loss and I like all the treble I can get to even things out.
