CD Player Question

I have a 97 sentra and i was taking out the existing after market CD player to put in a new kenwood cd player, well when i went to install my kenwood cd player it wouldn't work. I checked all the fuses in my car and on the cd player and nothing happened. I tried hooking up the one i had just taken out but it didn't work either. If anyone can help me or tell me if theres any other fuses or anything else i need to check that would be great.

Thanks, Matt

did you get a harness adaptor or try and nigrig the wiring? id check your wiring job again. and pls use a solder gun. dont twist and tape.

I double checked all the wiring, and i got the correct harness for it...It seems like a fuse is blown or something but i've checked all of them twice!
