I had this *exact* thing happen to me.

Empeg mk1 in my old (naff) polo. Broke in to find out if I'd put it in glovebox/under seat. Nicked my amp tho, the [censored]s.

Bought a blank faceplate and they *never* broke back into the car. (It looked like there was NO stereo in the car - wouldn't work on expensive cars).
