Sphengali had a 1995 Ford Explorer with an Alpine and an empeg, but his install is likely a bit different. A shame his site is blocked and archive.org didn't capture all of his great pictures. I thought most Ford and GM trucks had a 1.5 DIN or something slightly less than 2 DIN.

I have a double din space in my Volvo and it has a center DIN separator. My alpine fits below and empeg fits above just nicely. The separator holds everything in place very well. Maybe there's an alternative to cutting that out.
