8v8v - I've got Alpine Type R's in mine: SPR-176's - screwed in TIGHT, they'll get scraped by the window, but if you mount them on some reasonably firm rubber rings, then they're fine... the original grills don't QUITE fit back on perfectly, but I think that's more down to worn/broken clips than the speakers being that far out - driver's side was fine, but passenger's kept on popping off, so I just put a dab of contact adhesive on the back of each screw (both sides) and they're good as gold now.... the one time I've had to remove them (window electrics problem), I just peeled off the adhesive and added another dab onto each when I clipped the grills back in.
