I called crutchfield, and they have no information on allroads or s4s

This surprises me. Are those cars very new models? (i.e., this is the first year they've been out?) That would explain it, although Crutchfield is usually pretty good about supporting even new cars.

Anyway, sorry to hear about that. Looks like it's up to you (or up to another stereo shop willing to tackle it).

If the dash opening is truly double-din, then you could pair the Empeg and an aftermarket DIN CD player fairly easily. You could bypass the Bose system completely and run your own speaker wires (and if desired, amplifiers).
