Head unit issue

[Uberrstunts]

I'm installing a head unit in my 2002 grand prix. And it was all working fine and after I did some work on installing my amp the head unit stopped working. I rechecked all the wires and they're connected properly. I noticed my head unit only lit up about half way and the display didnt turn on. So I re did all the connection and its still not working. I checked my fuses and the fuse fro my radio was blown. So I replaced it and I put in my old head unit and it's not getting any power at all now.

I'm totally lost, any ideas?

try connecting the power and the ground wires directly to the battery, if that doesnt work, its a blown fuse or a ****** HU

You have a fuse blown somewhere, check all of them.....

did you actually use a dmm and check ALL the fuses.
