No it is not neccessary and yes chances are you wired it wrong.

Where did you ground the radio at? Some of the old hyunday's (don't care) are common ground as well.

If the radio resest after you turn the car off, then you don't have a constant 12v. Use a Multi Meter to double check all the wires in the harness are the correct ones. Double check your fuses as well.
