Crutchfield may not give you the exact depth, but they will list the speakers that will definitely fit, and the speakers will have specs. Therefore you can determine the depth that way. But basically a good safe bet is a set of Sony Xplods or pioneer. They are the best sounding, shallow speakers out there, for the money I think, being inexpensive too, and they will definitely fit. It is a safe bet, and you can pick them up at wal-mart for a great price.
