Just the obvious really.... If the after market one didn`t work either , it looks as though you`ve either blown the fuse or wired it up incorrectly.............. Take the radio out and wire it up to a battery(or battery charger) and speaker on your workbench. This will prove whether it`s the radio or the car wiring. If the radio is OK , check the car wiring using a multimeter or test lamp.( Battery and Earth ...plus speaker wiring.
