Since the fuse started to blow after installing a radio. I would start by inspecting the wiring to the radio. If that gets you no results, then just disconnect the wiring harness that is not original to the car for the radio. If disconnecting the radio keeps the fuse from blowing, then reinspect the wiring to the radio, or you have a bad radio.
