Looking to replace the factory stereo and leave the amps and speakers in place, but I can't find a listing for a straight replacement. I also have a 90 Coupe (same dash & amp setup) and couldn't find anyone who had a clue about the amps.... "Rilly? Inna back? Ne'er seen that...."

Can't take any chances with this one - it's my wife's car. Straight up replacement - something with an Ipod interface. Any ideas? Any thoughts on why there are no listings for this car?
