Randolph, thanks for your help. I'm replacing factory installed radio
with MP3 head unit. I've Honda Civic '96. I checked the ACC fuse, it
was blown up. After I replaced it, the new audio system works only
when I connect its memory and power cables to main ignition cable. But
now problem is, it loses memory and all settings when I turn off the
car. When I connect the memory cable to 'actual' memory cable, it
doesn't work. I did checked backup and radio clock fuses, they look
fine (I even replaced them with other fuses). Any idea what can go
wrong with memory wire comming from battery? Is there any otehr fuse I
need to check? Any other alternates?

Thanks
