need help with aftermarket cd player

[BLACK MAMBA]

I have a aftermarket cd player, but my memory wire or (orange memory wire) does not have any power...i have to keep resetting my stations and time everytime i get in the truck...is there a fuse i need to check for this?

constant power should be yellow, this all depends on how the stereo was installed as it is aftermarket.

if you didn't install it yourself, and haven't done so before, take it to a professional.

otherwise, take it apart and verify the yellow wire is correctly wired in to your stock harness, preferably with an adapter harness so the factory stuff wasn't cut of spliced...
