Is it as simple as a 12v power supply??

If you are installing a new aftermarket head unit to replace an existing factory head unit AND the door speakers were working with the factory head unit, then read this thread:

If the system has already been modified by a previous owner, you may need to take some extra troubleshooting steps to figure out what is going on.
